Experimental apparatus is measured to non - smooth surface drag reduction of rotation type

The utility model provides an experimental apparatus is measured to non - smooth surface drag reduction of rotation type, including the experiment body, a centrifugal pump with be used for storing the fluidic pond for providing power, the fluid flow entry of experiment body is said with the water outlet pipe of centrifugal pump and is communicate, the fluid flow export of experiment body is passed through the pipeline and is introduced in the pond, the water inlet and the pond pipeline intercommunication of centrifugal pump, the experiment body includes the runner base, a casing for simulating the runner, resistance regulation and control subassembly and controller, resistance regulation and control unit mount is inside the casing, the resistance regulation and control subassembly port corresponding with the controller is connected. The beneficial effects of the utility model are that: the fluid of experiment usefulness can recycle, and is energy -concerving and environment -protective, device simple structure, cost are low, exemplar easy dismounting, the experimental performance is strong and do not receive numerous advantages such as experimental enviroment restriction on every side, each item test requirement in can the fully provided process of the test.
