Abstract.The study of the problem of the axi-symmetric stagnation flows towards a moving plate of micro-polar fluids is considered. The equations of motion are reduced to dimensionless forms and solved numerically using S.O.R. method and Simpson's rule, for three different combinations of the three parameters involved. Results are given in the tabular as well as graphical form and compared with the known results of Newtonian fluid. The accuracy of the numerical solutions is checked using four different grid sizes. This type of stagnation flow has application in certain cooling processes a coolant is impinged on a continuously moving plate.
