Application of SARIMA in Forecasting Energy Consumption and CO2 Emissions in Vietnam up to 2030 Thuy T.Bich Hoang, Thi Men Tran, Ngoc Doanh Le, Du Nguyen, Ngoc Anh Nguyen, Malayathi Sivaramakrishnaiah International Journal on Advanced Science Engineering and Information Technology, 2026 Vietnam's rapid industrialization and urbanization have driven unprecedented energy demand growth, posing challenges to energy security, sustainability, and SDG 7 compliance amid rising carbon dioxide (CO₂) emissions. Vietnam has experienced rapid growth in energy consumption over the past few decades, driven by industrialization, urbanization, and rising living standards. Vietnam relies heavily on fossil fuels such as coal and oil, which have contributed to increasing CO₂ emissions. As a result, Vietnam is now one of the fastest-growing sources of greenhouse gas emissions in Southeast Asia. Therefore, this study addresses critical gaps in long-term energy forecasting for developing economies by applying Seasonal Autoregressive Integrated Moving Average (SARIMA) models to annual energy consumption data (1995-2023) sourced from the World Bank, International Energy Agency, and Vietnam's General Statistics Office. High correlations (0.94-0.99) among population, GDP, energy use, and emissions underscore their interdependence, validating time-series approaches for univariate prediction. Optimal SARIMA models project a steady escalation in energy demand from 206.76 TWh (2024) to 253.70 TWh (2030), with narrow confidence intervals indicating predictive stability. CO2 forecasts reveal volatility, peaking at 503.59 Mt (2029) before declining, highlighting model sensitivity to historical shocks. Comprehensive diagnostics, including residuals, ACF plots, and rolling means, confirm a robust fit for energy trends but residual autocorrelation in emissions, suggesting the need for hybrid enhancements. These projections equip policymakers with actionable insights for infrastructure planning, renewable integration, and decarbonization strategies, advancing methodological frameworks for sustainable energy transitions in Asia.
Experimental and thermomechanical SPH and FEA model simulation using inconel 825 with tungsten carbide tool Malayathi Sivaramakrishnaiah, R. Meenakshi Reddy, A. Damodara Reddy, Prabhu Paramasivam, Praveen Kumar Kanti, Abinet Gosaye Ayanie Scientific Reports, 2025 This study introduces an integrated experimental and finite element analysis (FEA) simulation methodology for improving the turning process of Inconel 825 using tungsten carbide (WC) cutting tools. The research presents an innovative framework that integrates infrared thermal imaging with numerical simulations to examine transient temperature profiles and cutting forces across different machining settings. This study systematically examines the effects of feed rate, cutting speed, and depth of cut on thermal and mechanical responses, employing an L9 orthogonal array for experimental design, in contrast to usual investigations. This research's primary innovation is the exact monitoring of interface temperatures with an infrared thermal camera, yielding precise thermal data despite the difficulties posed by expensive materials and real-time heat dissipation assessment. The FEA simulations performed in Abaqus FEA utilize an elastoplastic material model exhibiting nonlinear behavior, effectively capturing yielding in both tension and compression. The results demonstrate a robust connection between experimental and numerical findings, with cutting force predictions differing by less than 5%. The research indicates that raising the cutting speed lowers cutting forces while influencing temperature patterns in a non-linear manner. The research underscores the significance of WC inserts in augmenting heat dissipation and promoting machining stability. The proven FEA framework provides a dependable prediction instrument for optimizing machining settings, hence enhancing process control and precision manufacture of high-strength alloys.
Eco-Friendly Air Pollution Control with Biodegradable Filters Using Glass Wool, Activated Carbon, Coconut Fibre, and Grass Sowjanya Madireddi, J. Sai Manidhar, N. Jaya Chitra, M. Sivaramakrishnaiah, Prabhu Paramasivam, Praveen Kumar Kanti, Mohamed Yusuf Aerosol and Air Quality Research, 2025 Pollution in the atmosphere leads to severe health-related diseases in living beings. The source of air pollution includes engines, factories, and mining leading to pollutants like CO, CO2, HC, and NOx along with dust and soot. Investigators have been working on reducing air pollution using different materials, however, the disposal of these filter materials upon usage in turn leads to pollution of the soil or water. In the present work, bio-degradable materials glass wool, coconut fiber, grass, and activated carbon have been tested and compared for their ability to reduce air pollution. The source of pollution shows that the CO and CO2 emissions have been observed high for low compression ratios, whereas HC emissions have been found high for higher compression ratios and Nox emissions high at medium compression ratios. For a compression ratio (CR) of 2.5, glass wool is more efficient than other filter materials. For CR. of 3.5, glass wool and coconut fiber have been observed as more efficient than other filter materials. For a CR of 4.67, grass has been more efficient than other filter materials in reducing CO, CO2, HC and NOx pollutants. Grass has been observed as the most efficient in reducing the NOx content for compression ratios 2.5 and 3.5. Coconut fiber has been effective in reducing NOx for a 4.67 compression ratio.

Influence of nano titanium dioxide on strength and durability of ambient-cured GGBS-based geopolymer concrete A. Ravi Theja, M. Sivaramakrishnaiah, K․V․S․Gopala Krishna Sastry, C. Sashidhar, Prabhu Paramasivam, Praveen Kumar Kanti, Abinet Gosaye Ayani Results in Engineering, 2025 This study investigates the impact of nano titanium dioxide (nano TiO₂) on the mechanical and durability performance of geopolymer concrete (GPC) produced using ground granulated blast furnace slag (GGBS) and ambient curing conditions. Sodium hydroxide (10M) and sodium silicate were used as alkaline activators at varying ratios to determine the optimal mix design, with the best compressive strength observed at a Na₂SiO₃/NaOH ratio of 2.5. Nano TiO₂ was then incorporated into the GPC in varying dosages from 1% to 5% by weight of GGBS. Compressive, flexural, and splitting tensile strength tests were conducted, along with rapid chloride permeability, water absorption, sorptivity, and resistance to sulfate and chloride attacks. Microstructural properties were assessed using SEM, EDS, TGA/DSC, and FTIR analyses. The optimal nano TiO₂ content was found to be 3%, which led to a 21.5% improvement in compressive strength and enhanced durability, with lower permeability and porosity compared to the control mix. Beyond 3%, performance declined due to nanoparticle agglomeration and microcracking. The results demonstrate that nano TiO₂ can significantly enhance the performance of ambient-cured GGBS-based geopolymer concrete when used within optimal limits.
Numerical analysis of energy dynamics in a bladeless turbine nozzle Malayathi Sivaramakrishnaiah, R Meenakshi Reddy, Annapurreddy Damodara Reddy, A Ravitheja, Prabhu Paramasivam, Mohamed Yusuf, Praveen Kumar Kanti International Journal of Low Carbon Technologies, 2025 A bladeless Tesla turbine, patented by Nikola Tesla in 1913, uses rotating discs to convert fluid flow energy into mechanical energy through viscosity and surface adhesion. This study presents the design, fabrication, and testing of a Tesla turbine with 100-mm diameter discs, a central exhaust, and replaceable nozzles. Computer-aided design modeling and computational fluid dynamics simulations optimized geometry, nozzle placement, and internal energy distribution, revealing insights into viscous losses and turbulence effects. Tested under pressures of 3–5 bar, the prototype achieved a peak efficiency of 8%, aligning with numerical predictions. These findings highlight the potential for bladeless turbines in low-pressure, micropower renewable applications.
Nano-thermal energy storage system for application in solar cooker M Sivaramakrishnaiah, B Surya Prakash Reddy, P V Subhanjeneyulu, N Sreenivasulu, B Veeralingam, Prabhu Paramasivam, B V Gurulakshmi International Journal of Low Carbon Technologies, 2024 Most of the household relies on an LPG cooking stove for meal preparation, with approximately 20 crore families across India consuming 1.5 lakh crores of LPG annually. Due to their dependency on open areas, present solar cookers are useless at night and morning, restricting usage to the afternoon despite sufficient solar radiation for 9–10 months. Phase-change materials and expensive thermal energy storage (TES) devices are needed for conventional solar thermal power facilities. An economical TES system using parabolic sun dish collectors is needed to decrease LPG import costs and pollution. In response, this project aims to design a solar parabolic dish collector coupled with a TES system, utilizing specially engineered carbon bricks to enhance heat storage and retrieval capacities while reducing initial costs. Employing ANSYS-CFX software, the TES system undergoes thorough examination. Computational fluid dynamics analysis is conducted to evaluate heat transfer coefficients for both the hot fluid, responsible for heating the bricks, and the cold fluid, which cools them. The results reveal heat transfer coefficients ranging from 15 to 20 W/m2 K for the hot fluid and 25 to 40 W/m2 K for the cold fluid, with the latter demonstrating higher coefficients attributed to air’s higher density compared to the hot fluid’s lower density. Overall, the TES system exhibits an estimated heat transfer coefficient of 20–25 W/m2 K, facilitating efficient heating and recovery of heat.
Numerical and experimental investigations on a bladeless turbine: Tesla's cohesion-type innovation Malayathi Sivaramakrishnaiah, Dhanajan Savary Nasan, Prabhakar Sharma, Thanh Tuan Le, Minh Ho Tran, Thi Bich Ngoc Nguyen, Phuoc Quy Phong Nguyen, Viet Dung Tran International Journal of Renewable Energy Development, 2024 The design, numerical simulation, manufacturing, and physical experimentation of Tesla's bladeless centripetal turbine for electrical power production are the topics of this research project. The turbine generates rotational motion in the discs by directing pressurized air and water tangentially across parallel smooth disc surfaces. The fluid speed parameter at the nozzle inlet determines the power generated. To ensure optimal mechanical design parameters, SolidWorks design software, fluid dynamics concepts, and machine element design were employed. The numerical simulation software ANSYS CFX was used. The numerical and qualitative findings of the models and physical experiments coincided well. The study revealed that the power production and turbine efficiency were regulated by the input sources and blade size. Variations in the fluid composition between the discs may additionally have an impact on the outcomes. The researchers investigated the connection between input fluid pressure and turbine efficiency, as well as the number of discs and turbine power. The prototype could generate 76.52 W of electricity at 50 bar pressure and 1.01e+05 Reynolds number. The operation was efficiently simulated using CFD, with only a 9.3% difference between experimental and simulated results. Overall, this research provides an in-depth assessment of Tesla's bladeless centripetal turbine. It verifies the design and numerical simulation methodologies used, as well as identifies the essential aspects impacting turbine performance and efficiency. The findings contribute to a better understanding of the turbine's behavior and give ideas for improving its performance.
