| Popis: | The flow an heat transfer on the unstea y laminar mixe convection boun ary layer in a micropolar flui past a vertical we ge have been stu ie taking into account the effect of magnetic fiel . We assume that the free stream velocity an surface temperature oscillate in magnitu e but not in the irection of the oncoming flow velocity. The governing equations have been solve numerically by using the straight forwar finite ifference metho . The amplitu es of skin friction an couple stress are foun to be significantly epen ent on the Richar sons number, Ri , the magnetic parameter, M , an the vortex viscosity parameter, K . We observe that the amplitu es of skin friction an couple stress increases owing to an increase of the Richar sons number, Ri , while these become lower for the higher value of the magnetic parameter, M , an the vortex viscosity parameter, K . Also the results emonstrate that the effects of the parameters on the amplitu es of heat transfer are rather weak. Dhaka Univ. J. Sci. 64(1): 65-70, 2016 (January) |
