查询词典 cavitating

A high-speed camera is used to visualize the flow structures,and Laser Doppler Velocity is employed for velocity measurement.The osculations are conducted on the two-dimensional hydrofoil section,based on a single-fluid model of the cavitation:the liquid/vapor mixture is considered as a homogeneous fluid whose eompsition is regulated by mass tranfer equation.The RNG k-ε turbulence model with modified eddy viscosity coefficient is used for computing,and the coefficient is related to the vapor and liquid densities in cavitated regions for simulating the cavitating flow.
