| description | The invention provides a boundary layer grid solving method of the underwater glider lift-drag ratio at different attack angles. The method aims at determining the optimal sliding angle of an underwater glider, obtaining resistance and lifting force at different attack angles and providing theory support for later selection of a control system and a power source of the underwater glider. Finally, the accuracy of boundary layer grid numerical simulation is verified through an experiment, and the obtained matching condition is good. The analysis method can be popularized to other series of underwater motion machines, and compared with traditional complex formula derivation, the calculation period is saved, calculating efficiency can be improved by two times or above, and the efficiency and other problems of the underwater machines can be predicted and solved more effectively. The method comprises the steps that A, an underwater glider physical model is simplified; b, an underwater glider fluid outer area model |
