Abstract

The article is to examine the simulations influence of exponential solar radiation and dissipative transport of steady mixed convective hybrid nanofluid flow regime for an incompressible fluid in the boundary layer limit past a non-isothermal moving thin needle. We solved the system of ordinary differential equations obtained by choosing appropriate non-dimensional variables using the MAPLE software scheme. We have discussed the flow behaviours and all physical quantities of interest like skin friction cofactor, rate of heat transfer and rate of mass transfer as a function of similarity variables and governing parameters. Our numerically calculated solutions are given with similar studies. For instance, the entrance of several parameters like mixed convection, Power Law constant, buoyancy ratio parameter, Eckert number are illustrated graphically on velocity, temperature and nanoparticle concentration profiles. We observed that, the rate of heat transfer is higher in all cases but the reduction of mass transfer rate has been noticed.
