A novel spatial–temporal prediction method for the effects of fish movement on flow field based on hybrid deep neural network

Engineering Applications of Computational Fluid Mechanics, Год журнала: 2024, Номер 18(1)

Опубликована: Июль 4, 2024

In the fish passage facility design, understanding coupled effects of hydrodynamics on behaviour is particularly important. The flow field caused by movement however are usually obtained via time-consuming transient numerical simulation. Hence, a hybrid deep neural network (HDNN) approach designed to predict unsteady around fish. basic architecture HDNN includes UNet convolution (UConv) module and bidirectional convolutional long-short term memory (BiConvLSTM) module. Specifically, UConv extracts crucial features from graph, while BiConvLSTM learns evolution low-dimensional spatio-temporal for prediction. results showcase that achieves accurate multi-step rolling predictions effect fields under different tail-beat frequency conditions. average standard deviation PSNR SSIM proposed model 60 time-step entire sequences four test sets being respectively larger than 34 dB 0.9. delivers speedup over 130 times compared simulator. Moreover, demonstrates commendable generalisation capabilities, enabling prediction spatial–temporal within even at unknown frequencies.
