Combined impact of viscosity variation and Lorentz force on slip flow of radiative nanofluid towards a vertical stretching surface with convective heat and mass transfer

This study is conducted to examine the influence of temperature dependent viscosity on slip flow over a convective sheet. Brownian motion and thermophoresis effects are taken into consideration in the presence of applied magnetic field and Joule heating. The emerging nonlinear problem is presented a...
