Exploration of Fluid Flow and Heat Transfer Between Two Co-axial Infinite Rotating Porous Discs
摘要
Presently, scholars are directing their attention towards the investigation of fluid dynamics and the transfer of thermal energy between two infinitely rotating porous discs that are coaxially aligned. The governing equations encompassing the velocity profiles, momentum equations, and heat distribution have been duly formulated. The solutions acquired encompass a spectrum of squeeze and rotational Reynolds numbers. Various physical characteristics, including the skin-friction coefficient, Nusselt number, and Prandtl number, have been evaluated over a wide range of Reynolds numbers. The effects of Reynolds number, Darcy number, vortex viscosity parameter, and Prandtl number on the flow field and temperature distributions have been determined and discussed. The experimental findings suggest that varying Darcy numbers and vortex viscosity parameters lead to differential shear stress values, with higher magnitudes observed for suction velocity and lower magnitudes observed for injection velocity. Furthermore, empirical observations have revealed a positive correlation between the rate of thermal energy transfer and the Reynolds number, irrespective of the suction and injection parameters. Furthermore, the thermal energy transfer rate decreases during injection but increases during suction, as the Darcy number and vortex viscosity parameter increase.
