Impacts of Nonlinear thermal radiation on a stagnation point of an aligned MHD Casson nanofluid flow with Thompson and Troian slip boundary condition

Abstract

This paper investigates the impact of the nonlinear radiative heat on the species heat transfer of a MHD Casson nanofluid flow with stagnation point associated with Thompson and Troian boundary conditions. In the study, the flow system is considered in a Dacry-Forchheimmer porous media in the presence of combination nonlinear thermal radiation and Thompson and Troian slip boundary conditions. With the aid of suitable transformation quantities, the governing appropriate model for the physical phenomenon is transformed into a dimensionless equation, and solutions are obtained numerically by employing the spectral collocation method. The influences of pertinent fluid physical terms on the thermal and species transfer of a MHD Casson nanoliquid are carefully studied. The qualitative outcomes on the investigation are reported in graphs and in tabular form. A comparative study of earlier results is made with the present and a quantitative agreement is found. The skin friction, local Nusselt number and local Sherwood number are as well analysed and the outcomes are offered in the table. The results reveal that the enhancement of the thermal relaxation parameter reduced the temperature of the fluid. Furthermore, the temperature is increased when temperature ratio, thermal radiation, Biot number, Eckert number, and Casson parameter are enhanced. Hence, the results are useful in improving thermal science devices and increasing industrial out.
