摘要
The current assessment deals with thermal and solutal stratifications in two-dimensional mixed convection tangent hyperbolic fluid past a stretched surface in porous medium under the effects of magnetic field. Theoretical analysis is made for heat transfer and mass transfer by considering the effects of non-linear thermal radiation, chemical reaction, exothermic reaction. The governing model equations (PDEs) are transformed into highly nonlinear ODEs by using suitable transformations. The Homotopy analysis-based technique BVPh 2.0 is utilized to solve the transform nonlinear ODEs. The significant out-comes are delineated for distinct values of dimensionless parameters. The numerical values of drag coefficient, heat transfer and mass transfer rate are presented in tabular form. In order to validate the obtained outcomes, we compared the results with earlier published article and find good agreement. From the results it is concluded that velocity shows decreasing behavior for Wi, power law index n, M and porosity parameters pm and the opposite trend is observed for the mixed convection parameter lambda. In most of the engineering and real-world problems, skin friction is not desirable, so it can be decreased by decreasing the values of chemical reaction parameter, mixed convection parameter and buoyancy ratio parameter.
