Outline of Final Research Achievements

This research project aims at the substantial improvement of accuracy and robustness of numerical model for interfacial multiphase flows in unstructured-grids for engineering applications. Major efforts have been made on the development and validation of novel high-performance numerical model. The following main achievements have been obtained. (1) A third-order numerical dynamic core for unstructured grids with arbitrary shape elements and mixed elements has been constructed. (2) An accurate numerical method for capturing moving interface has been developed for unstructured grids of hybrid elements. (3) A high-fidelity general-purpose numerical framework for interfacial multiphase flows in unstructured grids has been developed. (4) An experimental data set for validating numerical models has been prepared and used to validate the numerical model developed in the project. This research project has established a high-performance numerical model with great practical significance.
