| Summary: | Abstract The integration of micropolar fluid in extrusion processes is critical for understanding and improving the manufacturing of materials that reveal microstructural effects. Extrusion is a commonly used process in sectors such as polymer, food, and metal processing, where a material is pushed through a die to form a product with a desired cross-section (e.g., films, sheets, fibers, tubes). The consequences of magnetic field, thermal radiation, and chemical reaction on the quality of the extruded product constitute a complicated and vital area of research. Hence, the current study is conducted to examine the flow associated with the transport of heat and mass of micropolar fluid across an expandable sheet in the company of an external magnetic field, thermal radiation, and chemical reaction. The problem is controlled by the energy equation for heat transfer, the species transport equation for mass transfer, and the Navier-Stokes equations for momentum. Following some conversions, the subsequent scheme of ordinary differential equations (ODEs) is numerically worked out by applying the Legendre-collocation approach. The velocity, temperature, and concentration profiles are analyzed in relation to the effects of thermal radiation, magnetic field strength, and chemical reaction rate. The findings reveal that the magnetic field will decrease the velocity but on the other hand it will increase the microrotation velocity. The magnetic field and the thermal radiation will enhance the temperature. Finally, the magnetic field will improve the concentration slightly but on the other hand the chemical reaction will decrease it. |
