In the current work, a new approach based on exponential functions is presented to reach the exact solutions to the problem of natural convection about a full cone which is set in a porous medium for the both states of prescribed surface heat flux and wall temperature. The solutions are described in the form of the exponential functions series with unknown coefficients while the operational matrices...
In this paper two common collocation approaches based on radial basis functions have been considered; one be computed through the integration process (IRBF) and one be computed through the differentiation process (DRBF). We investigated the two approaches on natural convection heat transfer equations embedded in porous medium which are of great importance in the design of canisters for nuclear wastes...
