Experimental device suitable for testing friction resistance of jet flow surface and non-smooth surface

The invention aims at providing an experimental device suitable for testing friction resistance of a jet flow surface and a non-smooth surface. The experimental device comprises a test module, a drive module, a water supply module and the like. When viscous friction resistance is generated by moving fluid and an inner cylinder wall, the resistance is converted into torque, and the torque is transmitted to a water distribution hollow shaft. A cantilever rod is used for being matched with the water distribution hollow shaft, the friction resistance is amplified according to a certain proportion and converted into thrust, and the thrust is output. The thrust is output to a digital readout push-pull force meter on the upper portion of a dynamometer base through a sensing rod matched with the end portion of the cantilever rod, the thrust is recorded by a computer, and data processing is performed by the computer. The experimental device is small in size, low in construction cost, low in noise, convenient to mainta
