This product is an experimental equipment used to study the surface friction resistance characteristics of rotating bodies in fluid mechanics. By using valves and variable frequency regulation to generate a continuous and stable low turbulence test flow field, combined with different test sections and models, comprehensive disciplines such as flow field boundary layer, thrust, resistance, and bionics can be applied and tested. The equipment mainly consists of a contraction section, an experimental section, a diffusion section, an axial flow pump, a rectification section, a steady flow section, an experimental section, and a model.
