考虑热力学效应的水翼空化流动研究
Study of Hydrofoil Cavitation Flow with Thermodynamic Effects
摘要
Abstract
To investigate the influence of thermodynamic effects on cavitation flow characteristics,this study adopted two thermodynamic correction methods to modify the Zwart-Gerber-Belamri cavitation model.Numerical simulations of cavitation around NACA0015 hydrofoil were compared with experimental data.Results demonstrate that the modified cavitation models show good agreement with experimental results and can effectively predict thermodynamic effects on cavitation.Thermodynamic effects induce temperature reduction in cavitation regions,suppressing cavitation development,with their influence intensifying as temperature increases.The Fourier's law-based correction model exhibits superior performance in modification effectiveness.Flow loss analysis based on entropy production theory reveals that velocity gradient-induced entropy production dominates the total entropy generation,accounting for over 97%.Thermodynamic effects improve flow field structures and reduce turbulent fluctuations,thereby decreasing energy loss.However,temperature gradient-induced losses remain negligible compared to those caused by velocity gradients.关键词
