Simulation of Scott-Russell Wave Generator Utilizing Stabilized Moving Particle Semi-implicit Method

چکیده مقاله

In this study, a modified Incompressible Moving Particle Semi-implicit (I-MPS) method is used for simulating solitary wave caused by Scott Russell wave generator. This problem is an example of falling rock avalanches in reservoirs. Different kernel functions are used to simulate this problem and some of them modified for MPS method. Moreover, the problem is simulated by FLOW-3D software and Weakly Compressible MPS method for each kernel used in I-MPS method. Obtained results are compared to each other. The pressure fields are gained smooth by used I-MPS method. Numerical pressure field far from the wave generator which is not affected by wave generator is almost equal to hydrostatic pressure shows the ability and the accuracy of the used I-MPS method. Finally, the results of the numerical free surface are compared with those of analytical and good agreement achieved despite of using coarse particles size.
