An integral treatment for combined heat and mass transfer by natural convection in a porous medium

Coupled heat and mass transfer by free convection over a truncated cone in porous media: VWT/VWC or VHF/VMF

“…The variable grid parameter is 1.001 and the value of the edge of the boundary layer r~o~ is 10. It is worth noting In order to verify the accuracy of our computer simulation model, we have compared our results with those of Cheng et al [12], Bejan and Khair [2], Nakayama and Hossain [6], and Singh and Queeny [7]. The comparisons in the above cases are found to be in good agreement, as shown in Tables 1-4.…”

“…Heat and mass transfer about vertical cylinder in saturated porous media is analyzed by Yticel [4], [5]. Nakayama and Hossain [6], and Singh and Queeny [7] used an integral method to solve the problem of Bejan and Khair [2]. Lai et al [8] investigated the coupled heat and mass transfer by natural convection from slender bodies of revolution in porous media.…”

An integral treatment for heat and mass transfer along a vertical wall by natural convection in a porous media

“…Recently, Lai and Kulacki [2] have re-examined the free convection boundary layer along a vertical wall with constant heat and mass flux including the effect of wall injection. The heat and mass transfer by natural convection near a vertical wall in a porous medium under boundary layer approximations has been studied by Nakayama and Hossain [3] and Singh and Queeny [4]. A further review of coupled heat and mass transfer by natural convection in porous medium is given by Nield and Bejan [5].…”

An Integral Treatment For Coupled Heat and Mass Transfer By Natural Convection From A Radiating Paraboloid In A Porous Medium

“…This method with great freedom and precision provides highly accurate approximations to non-linear problems. On account of this reason only, Nakayama and Hossain [12], Singh and Queeny [13], Bansod et al [19], Singh and Chandarki [20] and Singh and Sharma [21] have successfully applied this integral approach to find analytical solutions of equations governing the combined heat and mass transfer by natural convection in porous media for various geometries. The radiative effects have important applications in physics and engineering.…”

“…Lai and Kulacki [11] generalized the problem tackled by Bejan and Khair [1] and obtained the similarity solutions of the boundary layer equations adjacent to at vertical surfaces with variable wall temperature and concentration, together with aiding buoyancies. Nakayama and Hossain [12] and Singh and Queeny [13] obtained integral solutions for problems for aiding buoyancies adjacent to vertical surfaces. Angirasa et al [14] obtained the finite-difference solutions for natural convection with opposing buoyancy effects in a fluid saturated porous medium.…”
