An analysis is made to investigate the effect of inclined magnetic field on Casson nanofluid over a stretching sheet embedded in a saturated porous matrix in presence of thermal radiation, non-uniform heat source/sink. The heat equation takes care of energy loss due to viscous dissipation and Joulian dissipation. The mass transfer and heat equation become coupled due to thermophoresis and Brownian motion, two important characteristics of nanofluid flow. The convective terms of momentum, heat and mass transfer equations render the equations non-linear. This present flow model is pressure gradient driven and it is eliminated with the help of potential/ambient flow condition. Surface condition is characterised by Newtonian heating/cooling. The numerical solution by Runge-Kutta method with shooting technique results in important findings: formation of inverted boundary layer is to be regulated by adjusting the relative shearing effect of plate and free stream, increase in angle of inclination and thermal radiation ascribe to low flow rate and higher thermal diffusion, in presence of Newtonian heating at the bounding surface the temperature of the nanofluid decreases with the higher values of Casson fluidity; this may have a therapeutic application to control the temperature of blood or any biological fluid.
