| Popis: | A mathematical model is developed for the simulation of 2D turbulent flow over a periodic surface. An asymptotic solution is found which allows the estimation of the velocity field and tangential stress at a preset periodic form of a surface and rough peak heights. The solution allows the detection of the flow separation points and maximal tangential stress on the surface. The solution found for the near-bottom tangential stress is compared with experimental data on pressure regions of bottom waves and shows their good agreement. |
