“…Numerical simulations are commonly utilized in experimental research concerning wind, solar, and fossil fuel energy due to their effectiveness and utility [11,12]. Utilizing computational fluid dynamics (CFD) simulations enables the exploration of numerous variables within the combustion process [13,14]. One advantage lies in their capacity to assess diverse operational scenarios and predict field values across the entire domain, even in regions where acquiring measurements in experimental tests could disrupt the system's operation.…”

Numerical analysis of briquette performance reveals potential energy savings via optimized moisture content.• Findings suggest energy savings via optimization of moisture content in briquette production. • Briquette moisture optimization could lead to improved efficiency and performance, aiding sustainable energy.This study presents a comprehensive numerical investigation into the energy evaluation and determination of dry moisture content of briquettes, a vital aspect of renewable energy production. Utilizing advanced computational fluid dynamics (CFD) modeling and simulations, we explored key parameters impacting briquette combustion, such as moisture content, size, density, and temperature profiles. The research demonstrates that these factors significantly influence combustion behavior, with the CFD model accurately predicting mass loss curves and burnout times. The process was completed in 10 minutes, reaching a temperature of 300K and yielding gases consisting of CO2, CO, and H2O, while the devolatilization front was assumed to be at 325K. The drying front was estimated to occur within the range of 303K to 310K. This knowledge is pivotal in optimizing briquettes as a sustainable energy source, ensuring efficient energy conversion, and reducing environmental impact. By integrating engineering principles, thermodynamics, and computational modeling, our interdisciplinary approach addresses complex challenges in renewable energy. The research findings underscore the importance of refining and validating these models to advance the understanding and utilization of briquettes as a clean and eco-friendly energy alternative. In a world increasingly prioritizing environmental sustainability and energy efficiency, this research aligns with broader efforts to transition towards cleaner and more sustainable energy sources, offering prospects for a greener and responsible energy future.

“…When pressure is exerted, the viscosity of a non-Newtonian fluid changes, whereas the viscosity of a Newtonian fluid remains constant regardless of pressure. Given the extensive array of technological and industrial applications reliant on non-Newtonian fluids, researchers have increasingly focused their endeavors on exploring this field [11][12] [13].…”

The utilization of pseudostem juice and cassava juice as non-Newtonian fluids for quenching applications is examined in this study. These fluids' microstructural and thermal characteristics were investigated and contrasted with those of conventional quenching mediums. The findings demonstrated that these fluids have distinctive qualities that make them attractive substitutes for conventional quenching mediums. The tensile strength of the samples increased when quenched in pseudostem juice of bananas (PJB) at 30 0C and water at 90 0C, exceeding the as-cast value of 435 MPa. Quenching in PJB resulted in a higher tensile strength of at least 442 MPa. Additionally, the hardness value reached its highest point for the sample quenched in banana pseudostem juice at 30 0C and its lowest point for the sample quenched in water at 90 0C, which was 418 BHN. Although lower than its as-cast value, samples of ductile iron that were quenched in water exhibited a slight improvement in impact energy compared to those that were quenched in banana and cassava pseudostem juice. According to the microstructural analysis, the smallest grain sizes for ductile iron samples quenched in pseudostem juice of bananas were 0.18 µm, 0.235 µm, and 0.255 µm, respectively, when quenched at 30 0C. The findings of this study affirm the effectiveness of Pseudostem juice and Cassava juice as quenching media, opening doors to the development of more streamlined and sustainable quenching processes.
