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.
