Numerical Simulation of Free Surface Flows by Using Weakly Compressible Corrected MPS Method
Mesh-free particle (Lagrangian) methods such as Moving Particle Semi-Implicit (MPS) are the latest generation of methods in the field of computational fluid dynamics where large interfacial deformations and fragmentations exist. Due to their mesh-free nature, these methods are capable of simulating any kind of boundary/interface deformation and fragmentations. In this study the weakly compressible corrected MPS (WCC-MPS) method is used to simulate dam break over a dry bed, which is a highly erosive and transient flow problem. The developed numerical model is first validated using a dry bed dam break problem by comparing with experimental data. Comparisons between the model results and experimental data showed that the developed numerical model with WCC-MPS method can well represent the dam break problems with very large free surface deformation and fragmentations.
