Abstract

En 中文

• A COA-driven CNN-LSTM surrogate framework is proposed for elbow erosion prediction. • COA serves as a unified global optimizer for both temporal and spatial branches. • A cascaded pathway links operating conditions, particle dynamics, and wall erosion. • The model is trained and validated using 625 experimentally validated CFD cases. • The proposed model achieves R² ≈ 0.972 and reduces RMSE and MAE by about 60 %.
