Visualization of the fountain flow in a piston driven non-Newtonian flow is studied by means of experiments and numerical computation. The result will be applied to the multilayer injection molding technique, where an accumulator is used, to store the polymer melt. The discontinuity at the contactline of the piston and the wall of the cylinder appears to have considerable influence on the total deformation history.
