Abstract:
T his paper descr ibes a study of the natural co nvection w ith heat and mass t ransfer induced by internal heat g ener at ion in a vert ical cylinder po rous medium, the natur al conv ect io n is driven by buo yancy ef fect due to temperatur e variat ion. T he dimensionless equat ions are o btained by int ro ducing st ream funct ion, using the contr ol volume fo rmulation. And the natural convect io n in a porous medium has been studied by numerical calculat ion including the f low f ield, temperature and concent ration prof iles. T he ef fect s of Ray leig h number R a and Lew is number Le on heat and mass t ransfer of a poro us medium hav e also been numer ically studied.
