 This paper examined the effects of various parameters on the flow, heat and mass transfer of Casin nanofluids over an exponentially stretching surface. The parameters included Hall current, thermal radiation, heat saucer sink, Brownian motion, thermophoresis, magnetic field, and Prandtl number. The authors used a similarity transformation to transform the governing partial nonlinear differential equations into ordinary differential equations which were then solved numerically using the MATLAB BVP for C package. The results showed that the flow velocity was a decreasing function of the thermal radiation parameter and the behavior was observed for the Hall parameter as well. Additionally, increasing values of Brownian motion parameter reduced the nanoparticle concentration profile. This article was authored by Y. Sheresh Kumar, Shaikh Hussain, K. Robbunot, and others.
