摘要: Abstract A mathematical model is developed for steady state magnetohydrodynamic (MHD) heat and mass transfer flow along an inclined surface in ocean MHD energy generator device with generation thermo-diffusive (Soret) effects. The governing equations are transformed into nonlinear ordinary differential appropriate similarity variables. emerging two-point boundary value problem shown to depend on six dimensionless thermophysical parameters - magnetic parameter, Grashof number, Prandtl modified source parameter Soret number addition plate inclination. Numerical solutions obtained the coupled momentum, salinity (species) conservation, numerically, using Nachtsheim–Swigert shooting iteration technique conjunction Runge–Kutta sixth order scheme. Validation achieved Nakamura's implicit finite difference method. Further verification via semi-numerical Homotopy analysis method (HAM). With increase skin friction depressed whereas it generally increases parameter. Salinity magnitudes significantly reduced increasing Temperature gradient decreased (mass rate) also number. Furthermore, decelerated inclinations temperature thermal
