Design of a Simple and Demountable Experimental Device for Drag Reduction of Super Hydrophobic Surface

Abstract:

In recent years, super hydrophobic surfaces for fluid drag reduction effectively promote the development of drag reduction technique. For the experiment of surface friction test, traditional water tunnel device and popular PIV technique are both complicated and expensive. It is significant to design an experimental device which can be applied easily with little error. In this paper, we design a simple and demountable experimental device for drag reduction based on the calculation of resistance, friction and the specimen strain and deflection. Application technology of strain gauge sensor, the device could realize the drag resistance test on small friction. By means of analyzing the hydrodynamic of test section, we change and simulate partial structure of the test section to optimize the experimental apparatus. With the help of this device, we can measure small friction resistance directly by amplifying and output the small mechanical signals.
