Abstract

This paper describes an implicit finite element cavitation algorithm. The cavitation problem is formulated using the complementarity form. By using the complementarity formulation, the fluid pressure in the non-cavitation region and the density of the air/fluid mixture in the cavitation region are solved simultaneously. The stream-wise biasing approach is used to produce oscillation-free solution at the fluid film reformation boundary. Implicit scheme is implemented to yield stability for time marching. The algorithm is compared with the established finite volume methods, and the robustness and the correctness of the algorithm is verified.
