| Summary: | This paper studies the effect of g-jitter on free convection flow of a viscous and incompressible
micropolar fluid near the forward stagnation point of a two-dimensional symmetric body resulting from a step
change in its surface temperature. The transformed non-similar boundary layer equations are solved
numerically by an implicit finite-difference scheme known as the Keller-box method. The skin friction, rate of
heat and mass transfer has been studied for the effect of amplitude of modulation, frequency of oscillation and
micropolar parameters. The numerical results are given for the values of the Prandtl number Pr = 0.7 and
Schmidt number Sc = 0.94. A comparison with the earlier published results for Newtonian fluid (K = 0) shows
a very good agreement.
