| Some experiments have been made with the large rotating tank at the Institut de Mecanique de Grenoble to reproduce a sinusoidal flow along a vertical wall, over a flat bottom, with or without slope, in a homogeneous fluid. The objective of these experiments was to simulate a tidal motion, restricted to its main harmonic component M2, parallel to a vertical coast; and to demonstrate a particular mode of generation of residual circulation near the coast as a result of the interaction between friction, background rotation of the system (Ekman pumping) and oscillatory motion (Stokes effects). Moreover, the stabilizing (or otherwise) effects of the Earth's rotation on this shear flow may modify the rectification process. The configuration is in a good agreement... |
