Deformation of a Liquid Surface by an Impinging Gas Jet

Source abstract

The deformation of a liquid surface due to an impinging two-dimensional jet is considered assuming potential flow. This problem was solved numerically for small values of the Froude number $\lambda$ by Olmstead and Raynor (1964). By using a different numerical procedure we solve the problem for larger values of $\lambda$ up to $\lambda _2 \sim 6$. We show that the profile of the liquid surface contains a train of waves far away from the impinging jet.
