on non-Darcian mixed convection flow over an isothermal wedge embedded in a porous medium.
Abbas et al.[13] studied numerically bined effect of thermal dispersion and thermal
radiation on the non-Darcy natural convection flow over a vertical flat plate kept at higher and
constant temperature in a fluid saturated porous medium. Dulal and Hiranmoy[14] analyzed the
effect of thermal radiation on MHD convective heat and mass transfer from a vertical stretching
sheet adjacent to a non-Darcian flow in a porous region considering a more general Darcy-
Forchheimer-Brinkman flow model. Bakier et al.[15] studied the effects of melting, thermal
radiation, and temperature difference on a steady non-Darcy mixed convection flow from a
vertical wall embedded in a porous medium by using the group theoretic method. Recently,
Chamkha et al.[16] studied the effects of melting, thermal radiation, and heat generation or
absorption on a steady non-Darcy mixed convection flow from a vertical wall embedded in a
non-Newtonian power-law fluid saturated in a porous medium for aiding and opposing external
flows.
Additionally, coupled heat and mass transfer panied by melting effect in a porous
medium has received much attention in recent years because of its important applications
in permafrost melting, frozen ground thawing, casting and welding process, as well as phase
change material (PCM). Epstein and Cho[17] studied the melting heat transfer from a flat plate
in a steady laminar flow. Kazmierczak et al.[18–19] analyzed melting from a vertical flat plate
embedded in a porous medium in both free and forced convection processes. The heat transfer
at the melting surface in the laminar boundary layer by using Karman-Pohlhausen method is
discussed by Pozvonkov et al.[20]. Many studies have been reported to study the melting process
by the heat convection mechanism under a steady state[21–24] or unsteady state[25–28].
