Based on the CIP/Multi-Moment concept, a simple finite volume method, namely VSIAM3 (Volume/Surface Integrated Average based Multi-Moment Method) has been constructed and implemented to multi-fluid simulations. Using both VIA and SIA as the model variables, VSIAM3 has compact stencil and shows remarkable flexibility and robustness in a wide spectrum of simulations for complex fluids, thus is well-suited for inter facial multi-fluid flows. An simple algebraic scheme for capturing moving interface using hyperbolic tangent function, THING (Tangent of Hyperbola for Interface Capturing), is devised and incorporated to the VSIAM3 model. THING scheme exactly conserves the transported fluid fraction and, without the geometrical reconstruction as those required in the conventional VOF method, is very simple and easy to use.
