Abstract:

The paper presents the numerical simulation technology of deep-water risers’ fluid-solid interaction based on mesh-free MLPG method, which applies the combination of Petrov-Galerkin Method and three-step finite element method in the mode of separating velocity and pressure to discretize control equation of two-dimensional incompressible flow field respectively in time and space. At the end of the paper, a stationary cylinder Vortex-Induced Vibration is taken as an example to be calculated and compared. It is in good agreement with the traditional numerical method based on mesh and physical model well, which proves the proposed method is effective and has good accuracy.
