Abstract

<abstract abstract-type="main" id="fld4062-abs-0001"> <title>Summary</title> <p id="fld4062-para-0001">A moment‐of‐fluid method is presented for computing solutions to incompressible multiphase flows in which the number of materials can be greater than two. In this work, the multimaterial moment‐of‐fluid interface representation technique is applied to simulating surface tension effects at points where three materials meet. The advection terms are solved using a directionally split cell integrated semi‐Lagrangian algorithm, and the projection method is used to evaluate the pressure gradient force term. The underlying computational grid is a dynamic block‐structured adaptive grid. The new method is applied to multiphase problems illustrating contact‐line dynamics, triple junctions, and encapsulation in order to demonstrate its capabilities. Examples are given in two‐dimensional, three‐dimensional axisymmetric (<italic>R</italic>–<italic>Z</italic>), and three‐dimensional (<italic>X</italic>–<italic>Y</italic>–<italic>Z</italic>) coordinate systems.
