Newton's general similarity criterion was applied to the distorted model. Theresults for the similarities of gravity force, drag force and pressure force are identical withthose derived from relevant differential equations of fluid flow. And the selected limits of thedistorted ratio were studied and the simulation of roughness coefficient of distorted model wasconducted by means of hydraulic test. 展开更多
