Free convection slip flow of an exothermic fluid in a convectively heated vertical channel

Free convection slip flow of an exothermic fluid in a convectively heated vertical channel

The transient/steady natural convection flow of an exothermic fluid in a vertical channel considering the wall Navier slip condition and Newtonian heating is studied. Numerical solutions of the problem are obtained by using unconditionally stable and convergent implicit finite difference scheme. Due...
