INCLINED MAGNETIC FIELD EFFECT ON CASSON NANOFLUID FLOW IN A POROUS MEDIUM WITH JOULE AND VISCOUS DISSIPATIONS

Flow of a Casson nanofluid past a non-linear stretching sheet in a porous medium under the influence of inclined magnetic field is simulated numerically. Heat transfer characteristics are explored with combined impact of non-uniform heat source/sink, Joule and viscous dissipations. Partial differential equations (PDEs), representing flow, heat, and nanoparticles transfer are reshaped in non-dimensional forms by implementing a set of suitable transformations. Nonlinear coupled PDEs are solved by an effective numerical algorithm known as spectral local linearization method (SLLM). Flow, temperature and concentration profiles due to variation of parameters, namely, space- and temperature-dependent heat source/sink, Casson fluid parameter, Brownian motion, thermophoresis, Eckert number, Lewis number, and the magnetic parameter are underlined by replicating the numerical solutions in tabular and graphical forms. Analysis reveals that heat dissipation parameter has increasing influence on fluid temperature. Angle of inclination retards momentum whereas a reverse consequence appears in thermal field. Brownian motion and thermophoresis serve to enhance the fluid temperature.
