Abstract
In recent development CFD algorithms and schemes, a strong interest is focused on a new numerical method: meshfree method. In this thesis, the moving particle semi-implicit (MPS) method, one of the meshfree particle methods, is studied with a depth.
They are different in the means of function approximation and implementation process. Several typical meshfree methods were surveyed and classified. Both advantage and disadvantage of this kind of computational method were summarized.
Based on the previous research, the particle interaction models and the algorithm of MPS method were developed. Three examples, collapse of liquid column, drop impact on the liquid surface and floating body rolling in waves were successively simulated. Analyses were also made, which shows MPS of special advantage in simulating fluid free surface flow.
