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 fo und that the mass of the jet is as important as its momentum in determ ining the flow. For sufficiently long jets and small Froude numbers ai r cavities are entrained. Entrainment is more unlikely in two dimensio ns than in three.
