Abstract

The invention discloses a bionics-based underwater jet surface drag reduction test device, which comprises a jet part, a power input assembly, a water distribution assembly, a moving assembly, a magnetic fluid sealing assembly and a signal processing assembly, wherein the motor of the power input assembly is connected with the input shaft of the jet part via a first coupler; the output shaft of the jet part is connected with a torque signal coupler of the signal processing assembly via a second coupler; the signal processing assembly and the jet part are arranged on the moving assembly; the water inlet pipe of the water distribution assembly is connected with a water inlet pipeline of the jet part; the water outlet pipe of the water distribution assembly is communicated with the water outlet pipeline of the jet part; and the jet part is sealed via an axial sealing assembly. The bionics-based underwater jet surface drag reduction test device has the beneficial effects that the jet surface drag reduction effect test and the non-smooth surface structure drag reduction effect test can be realized, and when the jet surface structure drag reduction effect evaluation is carried out, and a test sample can be processed into a jet hole structure with a different aperture shape, a different aperture size, a different arrangement form and a different inclination angle.

Description

technical field [0001] The invention relates to a bionic-based underwater jet flow surface drag reduction test device. Background technique [0002] At present, the research results of drag reduction technology at home and abroad mainly include groove drag reduction method, soft wall method, bubble method, wall vibration drag reduction method, coating drag reduction method, polymer additive drag reduction method, joint drag reduction and bionic Jet surface drag reduction, etc. In view of the great significance of drag reduction, both at home and abroad are committed to the development of efficient and environmentally friendly drag reduction technology, and bionic jet surface drag reduction technology has always been one of the hot research issues at home and abroad. Its drag reduction effect is obvious, and the working process is environmentally friendly and pollution-free. For various drag reduction methods, it is necessary to have a test device to test the surface fricti...
