摘　　要：This article studies the three-dimensional boundary layer flow of an elastico- viscous fluid over a stretching surface. Velocity of the stretching sheet is assumed to be time-dependent. Effect of mass transfer with higher order chemical reaction is further considered. Computations are made by the homptopy analysis method （HAM）. Con- vergence of the obtained series solutions is explicitly analyzed. Variations of embedding parameters on the velocity and concentration are graphically discussed. Numerical com- putations of surface mass transfer are reported. Comparison of the present results with the numerical solutions is also given.This article studies the three-dimensional boundary layer flow of an elastico- viscous fluid over a stretching surface.
