Final Report Abstract

Although the project did not fulfill the original objective totally, we still achieved an very important scientific advances, e.g. SPH methods for two-phase flows with large density ratio, dual-time criteria and multi-resolution methods and their implementations on GPU. We really have faced a surprise in the course of the project, that is, the originally proposed GPU simulation platform is not able to handling the complex implementation associated with slug-flow simulation and analysis. At last, we did not have enough time to do more slug flow cases with sufficient high resolution.
