Dual solutions in mixed convection flow near a stagnation point on a vertical porous plate

The steady stagnation point flow towards a permeable vertical surface is investigated in this study. The external flow impinges normal to the heated plate and the surface temperature and velocity are assumed to vary linearly with the distance from the stagnation point. The governing system of partia...
