The elimination of long period waves has always been a difficult problem in coastal engineering that needs to be solved. Plate breakwater has a certain effect on long period waves, due to its convenience in construction, low cost and wide application range. Further research of which is of great significance. A numerical wave making flume is established based on Flow-3D in this paper, the optimal placement scheme and dimensions of the flat plate array breakwater are presented with the relative plate length L0/L, relative plate spacing j/L, relative plate thickness d/H and number of plates N identified as research parameters. Simulation results show that, when the relative plate thickness d/H=0.1, plate number N=4, relative plate spacing j1/L=0.3, j2/L=0.1, relative plate length L0/L=0.6, the wave suppression effect of non-uniform four-plate array breakwater is the best. It is shown that the arrangement form has good wave elimination for long period waves with period less than T=8 s (prototype period T=25.28 s).
