SIMULATION OF FREE SURFACES IN 3-D WITH THE ARBITRARY LAGRANGE-EULER METHOD

The arbitrary Lagrange-Euler (ALE) kinematic description has been implemented in a 3-D transient finite element program so as to simulate multiple fluid flows with Surfaces and interfaces of general shapes. The description of fluid interfaces includes continuity of velocity and a discontinuous tangential and normal stress appropriate for fluids of variable interfacial tension. The formulation is particularly relevant to the description of low and intermediate Reynolds number flow dominated by interfacial tension.
