Physical Modeling of Hydraulic Flows Hydraulic problems : • Analytical solutions usually not existing • Numerical solutions CFD huge computation demands for large-scale turbulent flows The most reliable solutions physical modeling. Also can test the design and the operation at a relatively small cost. A physical model needs to meet full flow similarities with the prototype geometric similarity, kinematic similarity and dynamic similarity. Therefore, may result in distorted models.
