Abstract

The authors show that the flow in front of advancing cylinders in piston-cylinder pumps is complex, giving rise to circulatory flows, which, in the case of repeated partial emptying of the cylinder, may result in very long residence times in it. They also demonstrate that it is experimentally not difficult to investigate this complex flow field in both the ″fountain″ and ″reverse fountain″ regions, utilizing tracer filaments of the same polymer containing a small amount of pigment. The total absence of molecular diffusion in polymer melts makes this tracer work possible. The final conclusion of this work is that both the ″fountain″ and the ″reverse fountain″ effects are verified and the existing theories are in semiquantitative agreement with the experimental observations.
