Exact Solutions for Mixed Convection Flow Near a Stagnation Point on a Vertical Surface in a Porous Medium

摘要

We analyze some of the equations regarding the unsteady mixed convection boundary layer flow using the symmetry properties underlying in the equations. These symmetries, in particular, approximate symmetries, provide a useful tool in the reduction of the equations, which, in this case, leads to exact, invariant solutions. We present three-dimensional graphical representations of the results for some cases of the constants and the mixed convection parameter.
