ABSTRACT: The impact of round and plane liquid jets on plane liquid surfaces is simulated numerically on the basis of a potential flow model. It is found that the mass of the jet is as important as its momentum in determining the flow. For sufficiently long jets and small Froude numbers air cavities are entrained. Entrainment is more unlikely in two dimensions than in three.
