采用泵喷补偿技术的近底拖体水压场数值模拟研究OA

In this paper,by using standard k-ε model and Fluent software,numerical simulation experiments are carried out to simulate the changes of pressure field generated by the underwater towing motion of a towed body using pump spray compensation technology.The results show that the use of pump spray compensation technology has little influence on the saddle-shaped distribution characteristics of the water pressure field of the towed body,but with the increase of the water spraying speed,the negative pressure at the head of the towed body increases slightly,while the negative peak amplitude in the middle section increases significantly.When water spraying speed reaches a certain value,the pressure characteristic curve of the towed body is close to the expected value,which proves that the pump spray compensation technology is feasible.
