Numerical simulation of partial-penetrating flow in horizontal convection

摘要：

We report the numerical simulations of the partial-penetrating ow in horizontal convection within a square cavity tank. The partial-penetrating ow was first reported in the experiment by Wang and Huang (2005), which is thought of important for understanding energy budget in ocean circulation. We find that sufficient large number of grids are necessary to eliminate unphysical oscillation of the solution. The fast startup but slowly steady ow is simulated, where a shallow and closed circulation cell is obtained numerically as partial-penetrating ow for the first time, which is consistent with the experiment. As the partial-penetrating ow is shallow, it is seldom affected by the bottom boundary.
