BACKGROUND: Small-scale industries (SSI) are the global economy’s backbone since most industrial workers are connected. Most of these workers are contractual and temporary without appropriate training. Also, the SSI does not have a standard workplace with an appropriate layout and infrastructure, as they manage with minimum resources. Therefore, the work hazards, i.e., musculoskeletal disorders and fatigue, often go unnoticed as holistic postural risk methodology is still scarce for identifying the awkward postures in SSI. OBJECTIVE: The present study proposes a novel holistic methodology to track and mitigate awkward postural risks in human-physical activities in SSI. To determine the effectiveness of the proposed methodology, a case study is presented in the South Indian Pump industry, wherein a critical workstation with a complex ergonomic work environment is employed. METHODS: An ergonomic evaluation was conducted empirically and numerically in the workplaces using Digital Human Models. In numerical evaluation, three virtual workspaces have been created to redesign the identified crucial workstation, focusing on ergonomics and workflow. RESULTS: The results obtained from the case study are encouraging for to use of the novel methodology in SSI. The case study reports that the proposed design significantly reduced the REBA score and WISHA lifting index by 6 and 1.20, respectively, without significant investment. CONCLUSION: The proposed methodology could encourage research to identify awkward posture in SSI.

Improving thermal performance while minimizing pressure differences and irreversibility characteristics remains a persistent challenge in thermo-mechanical systems. This study investigates a corrugated channel with different profiles (triangular, square, and elliptical) for steady, laminar, incompressible, and mixed convective flow through a backward-facing step. The impact of corrugated wall geometrical characteristics, such as height, width, and angle, on hydrothermal performance is explored. Additionally, the study investigates the influence of inline and staggered arrangements for various channel configurations. The finite element method is employed for numerical investigation of thermohydraulic and irreversibility characteristics. Results, presented through streamlines, contours, and line plots, reveal a significant modulation of reattachment length based on corrugate architecture. Notably, the local Nusselt number is highest at the initial interaction with the corrugated channel, regardless of the channel configuration. Hydrothermal measurements highlight elliptical configurations as optimal, exhibiting a 60% improvement in thermal performance compared to a non-corrugated channel. Moreover, increasing corrugate height results in higher Nusselt numbers, pressure drops, and irreversibility. Reduced corrugate width leads to a higher Nusselt number due to the formation of a secondary recirculation zone. An elliptical corrugate with a 0° angle inclination yields the highest Nusselt number by facilitating a stronger recirculation zone. Thus, optimal corrugated wall configuration involves higher height, lower width, and no angle inclination, emphasizing the significant impact of these parameters on hydrothermal performance and their importance as design characteristics.

The aim is to develop a computer-based assessment model for novel dynamic postural evaluation using RULA. The present study proposed a camera-based, three-dimensional (3D) dynamic human pose estimation model using 'BlazePose' with a data set of 50,000 action-level-based images. The model was investigated using the Deep Neural Network (DNN) and Transfer Learning (TL) approach. The model has been trained to evaluate the posture with high accuracy, precision, and recall for each output prediction class. The model can quickly analyze the ergonomics of dynamic posture online and offline with a promising accuracy of 94.12%. A novel dynamic postural estimator using blaze pose and transfer learning is proposed and assessed for accuracy. The model is subjected to a constant muscle loading factor and foot support score that could evaluate one person with good image clarity at a time.

In the present paper, plasma-assisted physical vapor depositions (PAPVDs) have been used to extract the TiN and titanium aluminum nitride (TiAlN). Further, plasma nitriding (PN) has been used prior to thin-film deposition of TiN on AISI 304 stainless steel material using intentional biasing (in the coating). PAPVD is integrated to investigate the thermal resistant effect coating of AISI 304 stainless steel by TiN coating using finite-element analysis. The morphology of elements on the coating was studied by field emission scanning electron microscopy, X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy. From XRD analysis, it has been observed that at the coated zone Ti, TiN was found on the AISI 3O4 stainless steel. The results in microhardness through the Vickers microhardness tester have been measured up to 350 Hv for the base sample at a 10 g load. Moreover, TiN/(PN + TiN) coated samples were measured with an average microhardness of 2220, 963, and 720 Hv for the nitride sample. In addition to this, the microhardness of TiAlN was found up to 1890 and 2400 Hv for different samples. The thickness of the film is around 1.4279 µm (TiN) and 1.888 µm (TiAlN) in 1 h of deposition.

Microchannel research has emerged significantly in the last decade due to its several applications, viz., heat exchanger, pharmaceutical, etc. Although several micro-machining processes have been developed in the previous few decades, the contemporary utilization of laser micromachining is minimal. In this context, the current research investigates the material characterization and thermal analysis of corrugated aluminum channels using an experimental and numerical approach. Herein, the types of equipment used are pulsed laser, scanning electron microscope, and energy-dispersive X-ray spectroscopy for experimental analysis. Moreover, the numerical investigation has been conducted using the finite-element method. The current study developed a numerical model for transient thermal analysis utilizing a Gaussian heat source. After that, the output data value is comparable to laser micromachining for experimental inquiry. The results of laser micromachining are shown in terms of heat affected zone (HAZ), depth, and width. The microstructural analysis revealed that the coarser grains are formed near HAZ, whereas finer grains with cracks are located near the laser focal point.

Enhancing cooling performance with the lowest pressure drop characteristics is a persistent problem in battery thermal management systems. The present investigation discusses the design of cooling plate pin configuration, especially for the fast charging–discharging operation of lithium-ion batteries. At first, the effect of pin geometrical configurations, viz. triangular, square, circular and elliptical, are studied for thermohydraulic characteristics. Further, orientation of the pin is investigated for normal and thermal runaway conditions. Furthermore, the effect of discharge rate and flow direction on thermal runaway behavior is also analyzed. Our results reveal that introducing pin on the cooling plate is desirable for better battery thermal management and keeping the battery surface temperature within safety guidelines. Further, the elliptical pin on the cooling plate is found to result in the least pressure drop (+80.46%) among pin configurations considered. The temperature of battery surface is found to be minimum when the pins are oriented at an angle of 90° to a flow direction of 180°, which is recommended particularly for the operation of the battery under thermal runaway. Furthermore, the pin configuration maintained cell surface temperature below 22°C and 75°C during normal and thermal runaway conditions, respectively. Moreover, the maximum pressure drop is found to be 225 and 136 kPa during normal and thermal runaway conditions, respectively.

The present works deals with the implications of non-uniform anode particle morphology on charging and discharging characteristics of Lithium-ion cell, especially for ultra-fast charging applications. The one-dimensional isothermal model is employed to analyze the effect of C-rate, porosity, tortuosity, and particle geometry for a range of non-uniform anode particle size distribution numerically. Our study reports that the value of capacity and specific power of the cell is found to be maximum when the particle size decreases along the electrode length. In contrast, capacity and specific power are minimum when anode particle size increase along the anode length. Moreover, a significant improvement in the performance of the Lithium-ion battery is found at ultra-fast charging when non-uniform particle distribution is employed. Additionally, a strong interplay of particle distribution and microstructural attributes viz. porosity and tortuosity on cell performance are revealed for the charging-discharging cycle. Further, the capacity of the cell is found to be maximum when the particle geometry is spherical. We anticipate that the results can inspire further improvement in ionic transport for ultrafast charging with non-uniform microstructure in the Li-ion cell.

AbstractThe present study numerically investigates the implication of different porosity configurations, viz., uniform, algebraic, trigonometric, logarithmic, and stepwise constant porosities at the negative electrode on performance characteristics of Lithium-ion cell. We assess the merit of nonuniform porosity over uniform one in terms of cell performance characteristics, viz., specific energy, capacity, electrolyte salt concentration, local volumetric current density, power dissipation density, and solid lithium concentration. Our results reveal that specific energy and capacity are found to be maximum when the porosity increases logarithmically in the direction from the negative electrode–current collector to negative electrode–separator interface. Also, it is found that the variation of power dissipation density and electrolyte salt concentration characteristics are dictated by the interplay of the porosity and the length of the negative electrode. Furthermore, the effect of charging rates (quick charge, fast charge, and ultrafast charge) on cell performance is carried out. It is seen that the increment in C-rates strongly influences the cell performance. It is found that the average capacity increases by 44% at the higher C-rate, i.e., 5C when the porosity increases logarithmically. On the contrary, sinusoidal variation in porosity yields in the worst cell performance. The findings of the present study bear utility toward designing an efficient battery system that can operate for a higher number of cycles with minimal power dissipation density and can fit into the ultrafast charging technique.
