摘要

AbstractIn this study, convection heat transfer around a solid circular cylinder embedded in porous media in the presence of magnetic field has been numerically investigated. Governing equations containing mass continuity, momentum and energy equations have been extended in polar coordinate system for porous media. The equations have been discretized by using a fmite volume method (FVM). The variables have been defmed in a staggered grid and a pressure correction-based iterative algorithm SIMPLE has been applied for solving the pressure linked equations. The range of Reynolds and Peclet numbers are between 1 and 40. Also Darcy number (Da) differs within the range of 10-7 and 10-2 and Magnetic parameter (M) varies between 1 and 10. The impact of Darcy number and magnetic parameter on the local and mean Nu number has been studied. It has been observed that the maximum amount of local Nu number increases with increasing Re number. It has been also deduced that the mean Nu number decreases with any increase i...
