Year: 2025

Type: article

Abstract: Recent developments in nanotechnology identifies the novel role of nanomaterials in upgrading the transport phenomenon of heat and mass transfer analysis. The significance of nanofluid is widely examined in energy enhancement, solar and nuclear systems, cooling applications, extrusion processes and various biomedical applications. This investigation contributes to bioconvective flow of Casson-Micropolar nanofluid due to porous bidirectional stretched surface. Unlike traditional models, a non-Fourier approach (Cattaneo-Christov model) is implemented to analyze the transport problem. The radiated effects and chemical reaction consequences are adopted to modify the model. The numerical computations are performed with help of shooting technique. It has been observed that the micro-rotational velocity due to porosity parameter while stretching parameter shows opposite results. The heat transfer impact enhances due to porosity parameter and micropolar fluid constant. The demonstrated results due to variation of flow parameters preserves applications in optimizing heat transfer efficiency, cooling impact, biofuels, fertilizers etc.
