Abstract

The invention, which belongs to the technical field of physical simulation of laboratory waves, provides a wave simulation method and device for a pool wave maker and a wave making device. On the basis of a full-domain method of combination of a virtual wave domain and a physical wave domain, a completely non-linear moving boundary differential equation between two domains is established and is processed by numerical discrete treatment and a wave-making signal is obtained directly. Different from the traditional linear analytical solution method, the provided method considers the nonlinearityof the wave completely and does not require calculation of the complex hydrodynamic transfer function in the frequency domain, so that the simulation accuracy and efficiency are improved effectively,the uncoordinated phenomenon of the wave plate motion is reduced, and the stability and effectiveness of wave physics simulation are enhanced. Moreover, the method having high universality and versatility can be adapt to the conventional single-sided linear wave-making machine, L-type wave-making machine, rectangular wave-making machine, circular wave-making machine, or other more complicated planar arbitrary-form wave-making machine systems.

Description

technical field

[0001] The invention relates to the technical field of physical simulation of laboratory waves, in particular to a wave simulation method, device and wave-making equipment for a pool wave maker. Background technique

[0002] In coastal, offshore or marine engineering, waves are a key hydrodynamic load. Simulating waves and studying their effects or damage mechanisms on structures can help people understand the threat of waves, so as to provide technical guidance for scientific research and engineering design. The physical simulation of ocean waves is an important method to study wave theory and an important means to solve various wave-related problems. The use of wave generators to generate physical waves in the laboratory is an important experimental method for studying wave propagation, breaking characteristics and their interaction with sea-related structures. The accuracy of the ocean waves simulated in the laboratory will directly affect the accuracy a...
