Краткое описание

This study numerically analyzed the Soret/Dufour effects on coupled heat and mass transfer by free convection over a vertical permeable cone in a saturated porous medium with internal heat generation and thermal radiation. The surface of the vertical cone has a variable wall temperature and variable wall concentration (VWT/VWC). The surface blowing/suction velocity is also variable. The similarity solution is obtained by internal heat generation in exponential decaying form. The Rosseland diffusion approximation is employed to describe the radiative heat flux. Similar governing equations are solved by the Keller box method. Comparisons showed excellent agreement with the numerical data given in previous works. Numerical data for the dimensionless temperature profile, dimensionless concentration profile, local Nusselt number, and the local Sherwood number are presented graphically for the exponent of VWT/VWC λ, buoyancy ratio N, Lewis number Le, internal heat generation coefficient A*, Soret parameter S, Dufour parameter D, lateral mass flux parameter fw, and the thermal radiation parameter Rd. The physical aspects of the problem are discussed in detail.
