WebApr 26, 2006 · The unsteady nonlinear potential flow induced by a submerged line source or sink is studied by a vortex sheet method, both to trace the free surface evolution and to explore the possible existence of steady-state solutions. WebFree-streamline theory is used to obtain exact solutions for free-surface flow problems. Boundary conditions for contact lines are introduced, and simple viscous flow problems with a free surface are solved analytically. Flow driven by wind shear is examined, and the surface drag coefficient id determined.
WebAn interface between a gas and liquid is often referred to as a free surface. The reason for the “free” designation arises from the large difference in the densities of the gas and … WebFeb 12, 2024 · The free-surface interface represents the dynamic upper boundary of an open channel flow system, therefore it seems reasonable to suggest that the free surface is also influenced by the same parameters.
