Abstract
The authors are developing a high-precision numerical simulation algorithm for gas-liquid two-phase flows to simulate gas entrainment phenomena in fast reactors. In this study, the calculation method for the unit vector normal to a gas-liquid interface in the high-precision volume-of-fluid algorithm (PLIC-VOF) is improved on two-dimensional unstructured meshes. The improved calculation method utilizes the least-square-fit of the height function defined at adjacent interfacial cells. In addition, to conserve the gas and liquid volume in the interfacial cell, the geometric relationship of a reconstructed interface and the cell is formulated. As the result of a basic verification, the improved calculation method succeeds in reproducing rectilinear interfaces on an unstructured triangular mesh. In addition, it is confirmed that the improved calculation method enhances the simulation accuracy of the well-known slotted-disk revolution problem on an unstructured mesh.
