Abstract

Highlights: VOSET + IDEAL is proposed for simulating 3D interfacial flow problems. The VOSET method is applied to capture the two-phase interface. The IDEAL algorithm is used to couple the velocity and pressure. VOSET + IDEAL can obtain accurate results for the problems with large ratio. VOSET + IDEAL can achieve the significant saving in computation time. VOSET + IDEAL is an accurate, robust and efficient method. Abstract: In order to accurately, robustly and efficiently simulate the three-dimensional (3D) interfacial flow problems with large density and viscosity ratio, we should, on the one hand, adopt the accurate and robust interface capturing method, on the other hand, use the efficient solution algorithm for coupling the velocity and pressure. In this paper, a coupled volume-of-fluid and level set (VOSET) method is applied to capture the two-phase interface, while an inner doubly iterative efficient algorithm for linked equations (IDEAL) is used to couple the velocity and pressure. Both of the VOSET method and the IDEAL algorithm were first proposed by the present author and further extended by other authors. Finally, the superiority of the VOSET method combined with the IDEAL algorithm (VOSET + IDEAL) is verified by three interfacial flow problems with large density and viscosity ratio.
