The results of studying the heat transfer process into mixed convection in a vertical circular microchannel occupied porous medium were presented. There is an estimation of Prandtl number effect on the temperature profiles and the heat transfer coefficient for various combinations of the values of the Knudsen and Rayleigh numbers.
