Scrutinization of Solar Thermal Energy On Heat and Mass Transfer Within a Micropolar Flow Over a Stretching Surface, Featuring Bioconvective Heat Generation and Chemical Reaction

Abstract

Enhancing heat and mass transfer efficiency is crucial for reducing energy consumption and mitigating environmental impact in various industries, including power generation, electronics cooling, and chemical processing. This study explores the impact of solar radiation, bioconvection, micropolar fluid properties, and nanoparticle and chemical reactions on a stretching surface. The research uses mathematical modeling and analysis to solve the 2-dimentional laminar bioconvection boundary layer flow of micropolar based nanofluids. The study concludes that bioconvection significantly enhances heat transfer and fluid flow characteristics, with heat generation and chemical reactions playing a crucial role. The thermophysical properties of the fluid, bioconvection parameters, and chemical reaction rates also have a significant impact on flow and heat transfer characteristics. The analysis reveals that increased heat generation leads to increased temperature, while chemical reactions decrease concentration flow. Unsteadiness parameters also impact velocity, energy, concentration, and microorganism. The findings can provide valuable insights for researchers and engineers in designing and optimizing heat transfer systems involving micropolar nanofluids with bioconvection, heat generation, and chemical reactions.
