Numerical analysis of MHD Casson boundary layer nanofluid flow over porous stretching surface with the effects of radiation and chemical reaction

Abstract

In this article numerical analysis of incompressible, two dimensional and mixed convective MHD Casson fluid flows over a stretching surface with porosity under the influence of radiation and chemical reaction as well as viscous dissipation considered. By utilizing suitable similarity analysis, the governing PDEs (Partial differential equations) with its respective boundary conditions were transformed to dimensionless forms. The resulting ODEs (Ordinary differential equations) along with corresponding boundary conditions were solved via shooting technique combined with Runge-kutta-Fehlberg method. The outcomes of this study illuminates that velocity, temperature and concentration fields decreases due to the thickness of the boundary layer as we go away from the stretching sheet surface and falling of velocity observed in Casson fluid parameter. Under some restriction the resultant outcome were compared with previous published results and is found in admirable agreement.
