NUMERICAL SIMULATION OF MICROPOLAR FLUID FLOW THROUGH A POROUS WEDGE WITH CHEMICAL REACTION AND THERMAL SOURCE/SINK USING THE RUNGE–KUTTA SHOOTING METHOD

Résumé fourni par la source

In the study, the micro-polar fluid flow travelling over a porous wedge under the action of the interaction between the heat transfer as well as the chemical reaction is analysed. These flows find applications in engineering, biomedical and industrial applications where rotating effects and microstructure play a major role on the transport behavior. However, because of nonlinear coupled equations, the solutions are difficult to determine analytically and this brings the need of useful numerical techniques. To solve this issue, we use a strong numerical solution using the Runge-Kutta shooting method to solve transformed ordinary differential equations. The method offers a strong and accurate determination of velocity, temperature and concentration gradient at various physical aspects such as delta, H, “Schmidt number (Sc)” and “wall parameter ((Fw))”. The findings indicate that the maximum velocity is attained at 1.5 and both temperature and concentration decrease rapidly towards almost zero in t 0 3-4. There is also an increase in the rate of heat transfer (Nusselt number 0.80 to 1.18 (a=47 percent) and 2.67 at larger values of K). On the same note, the Sherwood number rises by approximately 64%. Overall, the study will reach the conclusion that multiplication of (Fw) and other applicable parameters enhances the effectiveness of heat and mass transfer to enhance the effectiveness of the system.
