定常空泡 meaning in English
steady-state cavitation
Examples
- When the propeller operates in the spatially non - uniform velocity field behind the ship , the unsteady cavitation on the blades often causes the vibration of ship structure , the propeller noise and the cavitation erosion on the blade
在船尾非均匀流场中工作的螺旋桨，常常由于桨叶上产生了非定常空泡，导致船尾振动和螺旋桨噪声，致使桨叶表面出现空泡剥蚀。 - The prediction of propeller - induced hull pressure fluctuation in non - uniform flow is studied by using theoretical calculation and model experiment systematically . an intact method and computer program for the prediction of unsteady cavitating propeller - induced hull pressure fluctuation in non - uniform flow is set up in this paper . the measurement of propeller induced hull pressure fluctuation in depressurized towing tank carried out in this paper is the first time inland
