Performance Evaluation of a Mini–Vertical Axis Cross Flow Helical Turbine Meant for Energy Extraction from Dam’s Tailrace V. Jayaram, B. Bavanish, Mohammed Fahad, P. A. Azeem Hafiz, Niaz A. Salam International Journal of Renewable Energy Research, 2024 Research targeting renewable energy harnessing has gained considerable momentum in the past decade, given the decreasing status of fossil fuel reserves. Hydropower generates constitutes the lion's share of renewable energy worldwide. However, they continue to be underutilized. Hydropower generation from tailrace water offers significant prospects for micro hydro power generation, which, if effectively implemented, can help improve a power grid's rating. The primary purpose of this investigation is to determine the viability of vertical-axis cross-flow turbines with helical blades (Gorlov Helical Turbine) for deployment in such settings. Solidworks was used to model the Gorlov Helical Turbine (GHT). The GHT model is simulated using Ansys Fluent. The principal objective is to determine the turbine's performance at a velocity of 2.54 m/s. NACA 4412 was chosen as the helical blade's aerofoil. The study is validated by experimentation using a 3D-printed model. According to the simulation and experiment, the power (output) of GHT was 1.78 W and 1.24 W, respectively. The turbine's performance was adequate for deployment based on output power Vs tip speed ratio plots. The result substantiates the studies on the effective integration of cross-flow turbines in the tail race of a dam to increase the grid efficiency of SHPs
Nanoindentation and mechanical characteristics of TiO2/polypropylene polymer nanocomposite A. S. Favas, B. Bavanish Digest Journal of Nanomaterials and Biostructures, 2024 This research investigates the nano-titanium oxides (TiO2), impact on the composition, nano-indenter test, and mechanical characteristics of Polypropylene (PP). The incorporation of TiO2 nanoparticles into a solution of PP polymer led to the creation of a homogeneous blend. Hydraulic pressing yields a polymer nanocomposite rectangular sheet of 2 millimetres in thickness. In order to examine the nanocomposites, XRD (X-ray diffraction) and FTIR (Fourier transform infrared spectroscopy) were used. The dispersion of the nanoparticles was analysed using a field emission scanning electron microscope (FESEM). The addition of TiO2 nanoparticles at concentrations of 2 and 4 wt% was used to modify polypropylene, while the proportion of polypropylene remained constant at 1% weight. X-ray and FTIR analysis confirmed the existence of TiO2, whereas the SEM findings demonstrated the effective distribution of TiO2 throughout the PP matrix. An investigation was conducted to examine the impact of TiO2 on the mechanical characteristics of PP. The samples were subjected to mechanical characterizations utilising traditional methods such as flexural strength, tensile strength, impact resistance, and nanoindentation. The mechanical investigation revealed that the nano hardness of the changed coating, as measured by nanoindentation, exhibited a maximum increase of 36.9% in comparison to the unmodified coatings. The nanocomposites exhibited enhanced mechanical characteristics, with the nano hardness and elastic modulus of the nanocomposite samples surpassing those of pure PP.
Experimental investigation on the mechanical properties of Al2024 doped with green synthesized quantum dots Pushpa Raj Berlin Push, Balac Retnam Bavanish Revista Materia, 2024 This work used a novel technique known as powder metallurgy to create Aluminium (Al) 2024 matrix composites using Al 2024 reinforced with graphene quantum dots at concentrations ranging from 0.25 to 1 wt.%. Here, Al alloy 2024 is presented as a metal matrix composite reinforced with graphene quantum dots. Graphene quantum dots (GQDs) are fragments of graphene that are smaller than 100 nm in size. Graphene quantum dots are added to Al 2024 in proportions of 0.25%, 0.5%, 0.75%, and 1% to create composites. Atomic force microscopy, X-ray diffraction analysis, Fourier transform infrared, TG/DTA, transmission electron microscopy, and scanning electron microscopy experiments have been carried out to determine the characteristics of the synthesized GQD nanoparticles doped with Al 2024. This powder metallurgy process in Al 2024 offers a number of advantages. Shape and material flexibility, application variety, and cost-effectiveness are all made possible by these characteristics. The results showed that powder metallurgy is a suitable method for incorporating and dispersing nanoparticles into Al 2024.
Thermal and mechanical characterization of polypropylene composite membrane doped with TiO2 nanoparticles A. S. Favas, , B. Bavanish, and Digest Journal of Nanomaterials and Biostructures, 2022 The HVAC (Heating, Ventilating, and Air Conditioning) industry offers many opportunities for membrane-based gas separation technologies. In this study, a hollow polypropylene (poly-P) fibre membrane loaded with nanoparticles was created to dry out the indoor air. The mechanical and thermal stability of polypropylene loaded nanoparticles (TiO2/poly-P) usually improve with increasing titanium concentration. The example of poly-P with a 4% volume concentration of TiO2 nanoparticles in a polypropylene matrix shows the highest improvement in thermal stability. Atomic force and scanning electron microscopy were used to examine the nanocomposites' structure, and the results showed a correlation between the change in the thermal and mechanical characteristics and the change in TiO2/poly-P content. According to AFM investigations, when titanium nanoparticles are added to poly-P, the supramolecular structure is altered and an ordered structure is created. In comparison to 2% TiO2 doped poly-P nanocomposites, films containing 4% TiO2 demonstrated a more effective immediate moisture retention capacity, according to moisture absorption analyses. This study offers a fresh viewpoint for enhancing the poly-P composite membrane's ability to dehumidify the air.
Tribological and ageing behavior of Az91D magnesium alloy fortified with nano lanthanum and nanoceria by stir casting for aviation application Mohammed Fahad, Bavanish B. Industrial Lubrication and Tribology, 2021 Purpose The aviation field requires a material with the ability to withstand severe environmental conditions. The purpose of this paper is to provide higher wear resistance and improve the lifetime of aircraft. Hence, it is vital to enhance the wear resistance and strength of the material. Design/methodology/approach In this investigation, the Az91D magnesium alloy was reinforced with lanthanum (La2O3) and cerium oxide (CeO2) nanoparticles by stir casting and heat treatment process and the tribological and mechanical properties were analyzed. Findings The results showed the Az91D/CeO2 composite exhibited higher density (1.96 g/cm3) and lower porosity (1.01%) compared to other materials due to the diffusion of CeO2 nanoparticles in between the atoms of Az91D alloy. The hardness of Az91D/ CeO2 & Az91D/ La2O3 was improved by 38% and 34%, respectively, compared to Az91D alloy owing to the reinforcing effect of hard nanoparticles. Further, the inclusion of nanoparticles decreased the mass loss and showed lower wear rate compared to the Az91D alloy due to the pinning effect of nanoparticles. In addition, the friction coefficient was observed in the order of Az91D > Az91D/ La2O3 > Az91D/ CeO2. Moreover, the heat treatment displayed positive results on the properties of all the materials. Originality/value This work is original as the combination of cerium oxide nanoparticles with Az91D magnesium alloy is not tried by earlier investigators. Further, the comparative performance of both lanthanum and cerium oxide nanoparticles on the tribological and mechanical behavior of Az91D alloy has been analyzed for aviation application. This study will provide new information to the scientific world to increase the lifetime of aviation structures.
Tribological behavior of AZ91D magnesium alloy composite: effect of hybrid WC – SiO2 nanoparticles Mohammed Fahad, Bavanish B. Industrial Lubrication and Tribology, 2021 Purpose Aviation field requires a material with greater tribological characteristics to withstand the critical climate conditions. Hence, it is of paramount importance to enhance the wear resistance of material. AZ91D magnesium alloy is a light weight material used in the aviation field for the construction work. The purpose of this study is to augment the wear properties of AZ91D alloy by reinforcing with hard particles such as tungsten carbide (WC) and silicon dioxide (SiO2). Design/methodology/approach In this work, three types of composites were fabricated, namely, AZ91D – WC, AZ91D – SiO2 and AZ91D – (WC + SiO2) by ball milling method, and the tribological properties were analyzed using pin-on-disc apparatus. Findings Results showed that the hardness of AZ91D alloy was greatly improved due to the reinforcing effects of WC and SiO2 particles. Wear study showed that wear rate of AZ91D alloy and its composites increased with the increase of applied load due to ploughing effect and decreased with the increase of sliding speed owing to the formation of lubricating tribolayer. Further, the AZ91D – (WC + SiO2) composite exhibited the lower wear rate of 0.0017 mm3/m and minimum coefficient of friction of 0.33 at a load of 10 N and a sliding speed of 150 mm/s due to the inclusion of hybrid WC and SiO2 particles. Hence, the proposed AZ91D – (WC + SiO2) composite could be a suitable candidate to be used in the aviation applications. Originality/value This work is original which deals with the effect of hybrid particles, i.e. WC and SiO2 on the wear performance of the AZ91D magnesium alloy composites. The literature review showed that none of the studies focused on the reinforcement of AZ91D alloy by the combination of carbide and metal oxide particles as used in this investigation.
