Heat and mass transfer from truncated cones with variable wall temperature and concentration in the presence of chemical reaction effects

Abstract

Purpose -The purpose of this paper is to solve the problem of steady, laminar, coupled heat and mass transfer by MHD natural convective boundary-layer flow over a permeable truncated cone with variable surface temperature and concentration in the presence of thermal radiation and chemical reaction effects. Design/methodology/approach -The governing equations are derived and transformed into a set of non-similar equations which are then solved by an adequate implicit finite difference method. Findings -It is found that the presence of thermal radiation, magnetic field and chemical reaction have significant effects on the rates of heat and mass transfer. The variation of the wall temperature and concentration exponent contribute to significant changes in the Nusselt and Sherwood numbers as well. Originality/value -The titled problem with the various considered effects has not been solved before and it is of special importance in various industries. The problem is original.

“…The Hamilton and Crosser model [39] is used for the thermal conductivity of different shapes of CdTe nanoparticles. For validation purposes, some limited cases of the current study are compared with the numerical results provided in References [40,41], as shown in Table 4 and the results are in excellent agreement.…”
