Description

technical field [0001] The invention relates to a hydrofoil surface fluid resistance testing device capable of realizing jet flow. Background technique [0002] In recent years, bionics has been one of the hot issues of domestic and foreign researchers. For example, the bionic jet surface drag reduction technology derived from the gill slit jet function in the shark breathing process has obvious drag reduction effect and is an effective active control method, and its jet action can optimize the wall fluid The boundary layer structure then achieves the purpose of reducing the fluid frictional resistance of the solid wall. If this drag reduction technology can be applied to the drag reduction of the hull surface of underwater vehicles, it will play an important role in increasing the speed of the ship and saving energy. certain military role. There has been relatively little research on bionic jet surface drag reduction technology. The current research on jet mainly focuses ...
