Development Of Experimental Flume Wavemaker System And Numerical Simulation

Ocean waves is one of the most common physical phenomenon, and it's also one of the major dynamic loads suffered by coastal engineering structures, naval architecture and ocean engineering structures. The significance of research on waves and the interaction between waves and engineering structures is self-evident. Wavemaker is an important means to study the waves.In this paper, based on the wave flume in Shandong Jiaotong University port engineering laboratory, which is 50 meters long, 1.2 meters wide and 1.2 meters high, developed a wave flume control system by using wave simulation theory. It can be used to simulate regular waves: slight wave, cnoidal wave, soliton wave and irregular waves: standard spectrum, JONSWAP spectrum, B- M spectrum, P- M spectrum. The physical model tests of the proof system section of Tianjin Nanjiang Industrial Zone West Basin is conducted in the wave flume. The test results is significant on real engineering.In this paper, a numrical simulation of wavemaker process in wave flume is conducted by using the solver ih FOAM which is based on Open FOAM, an opensource CFD software. The effects of different methods of mesh on calculation accuracy and computational efficiency is researched. Numrical simulation of the proof system section of Tianjin Nanjiang Industrial Zone West Basin is executed. Comparing the result of physical tests and numrical simulation shows that the numrical simulation can get the consistent result with physical tests.
