Two-dimensional flow of a liquid sheet under gravity
An iterative finite difference technique is developed to simulate the free surface flow in a two-dimensional liquid sheet under gravity. The technique is based on an orthogonal boundary-fitted coordinate transformation; the streamfunction-vorticity formulation is adopted. The normal stress boundary condition is employed to update the free interface shape within the iterative process. Computed results agree well with data available in the literature for flows with and without gravity.
