Numerical Simulation of Irregular Waves in Shallow Water by Using Meshless Method

XIAO Long-fei,YANG Jian-min,LI Jun(State Key Laboratory of Ocean Engineering,Shanghai Jiaotong University,Shanghai 200030,China)  
By using the meshless method,a numerical ocean engineering basin was established to simulate irregular waves propagated in shallow water.Locating the source points outside the computational domain,the problem of water wave propagation was solved by collocation of only a few boundary points instead of meshes.Therefore,the meshless method without singular numerical integrations is easy to implement and the computational time can be economized.Through meshless numerical simulation and experimental validation on the propagation of wave profiles from deepwater to shallow water and iterated modification on the wave spectrums,eligible time series of shallow water irregular waves can be obtained.The numerical(results) of the wave spectrums,wave parameters and time series of the irregular waves agree well with the experimental results.
