Abstract:
This work conducts a numerical examination into the influence of a magnetic field and viscosity dissipation on the movement of a micropolar fluid over the surface of a vertical, hollow circular cylinder via conjugate mixed convection. In this investigation, we obtained a numerical solution for a non-linear differential equations-based modeling system by employing MATLAB and the bvp4c solver, which operates on a two-equation model. ; We show graphically how micropolar materials, conjugate heat transfer, viscous energy dissipation, buoyancy factors and magnetic field affect the temperature at the interface, local skin friction and heat transfer. By contrasting the acquired results with those found in the published research, which exhibit a high degree of concordance, the validity of the methodology is proven. ; The findings indicate that the escalation of the Eckert number correlates with an increase in both interfacial temperature and skin friction, accompanied by a reduction in local heat transfer. Furthermore, elevated magnetic and buoyancy values amplify both skin friction and thermal transfer, contributing to a decrease in dimensionless interfacial temperature distributions.
