MIXED CONVECTIVE NONSTEADY 3-DIMENSIONAL MICROPOLAR FLUID-FLOW AT A STAGNATION POINT

The problem of mixed convective non-steady three dimensional flow of a micropolar fluid near the stagnation point of a blunt nosed body has been discussed. The governing set of differential equations are solved using the Finite Element Method. The velocity and microrotation distr ibution are shown graphically to depend upon four parameters namely th e micropolar parameter, Grashof number, buoyancy parameter and the deg ree of acceleration. The conclusions are quite interesting from the ap plication point of view.
