DEVELOPMENT OF NEW MPS-BASED WAVE GENERATION MODEL

Abstract

 For practical use, a numerical wave flume requires the ease of the connection to the other numerical models which calculate waves in a larger area. In the particle-based numerical flume, a traditional wave boundary model with a piston-type wave paddle is widely used. However, it requires an additional tuning procedure to reproduce the desired input waves by the piston motion of the wave paddle. Therefore, it is difficult to apply the model to, in particular, irregular waves. To resolve this problem, a new wave boundary model is developed. The proposed model uses only the wave heights as the input data. Its good performance is shown through benchmarks targeting regular waves and a solitary wave. Moreover, its good conservation of the water levels is shown through the numerical simulations of overtopping waves.
