Abstract: A flow field identification method of artificial intelligence fish simulation system uses cluster server parallel sampling to obtain continuous flow field time series information data. After preprocessing the data, the method uses the lateral line perceptron of recurrent neural network or convolutional neural network based on long time series to continuously acquire data, train and iterate. Finally, the method can identify the flow field sequence data signal with time series property, wherein, the perceived flow field signals include but are not limited to velocity, pressure and vorticity, and the experimental results are continuously filled into the experimental database, which will have the effect of memory transplantation on the artificial fish and reduce the occurrence of repetitive errors. The method identifies the flow field of an artificial intelligence fish simulation system, which can fully reflect the characteristics of the flow field from the aspects of amplitude, frequency, and wavelength.

Abstract: The invention introduces a hydrodynamic free-surface Lattice Boltzmann (LB) simulation method and system, along with a storage medium. Initial parameters for a designated water body are obtained and fed into a pre-established three-dimensional hydrodynamic free-surface LB model for simulation calculations. The outcome includes precise data on the free water surface, flow velocity, and pressure of the target water body over time and space, generating a detailed three-dimensional spatial distribution map. The method enhances the second-order accuracy of the force term within the single-phase free-surface LB model. By integrating the single-phase free-surface LB model with surface tension and the SGS large eddy model, it achieves an efficient and accurate three-dimensional simulation of the target water body's free water surface, flow field, and pressure.
