Fountain flow is the phenomenon of deceleration and outward motion of fluid particles as they approach a slower moving interface. The use of a general purpose finite element program for the appropriate boundary conditions made possible the detailed flow description behind an advancing liquid front moving at constant speed inside two‐dimensional channels and tubes. The results were qualitatively the same for both Newtonian and shear‐thinning fluids.
