effect of mhd on casson fluid with arrhenius activation energy and variable properties

In the present study, mhd casson nanofluid under the influence of exponential temperature dependent thermal conductivity and variable viscosity past a stretching surface has been scrutinize. after the application of the similarity transformations, the governing partial differential equations of the modelled problem are converted into ordinary differential equations and solution is achieved with the assistance of the shooting method. the solution obtained with the help of shooting technique is used to analyze the distribution of mass and heat flux over sheet. the influence of various governing parameters on the dimensionless velocity, temperature and concentration distribution have been analyzed and discussed in detail. the simulations of the presented model show that the surface drag is upsurged as each of the casson parameter and temperature dependent thermal conductivity parameter is boosted whereas the rate of heat transfer is diminished. it is also observed that an increment in the temperature near the surface is noted against the thermal conductivity parameter whereas an opposite trend is observed away from the surface.
