| Zusammenfassung |
| An analytical solution of the Boussinesq equations for
the motion of a viscous stably stratified fluid driven by a surface thermal
forcing with large horizontal gradients (step changes) is obtained. This
analytical solution is one of the few available for wall-bounded
buoyancy-driven flows. The solution can be used to verify that computer
codes for Boussinesq fluid system simulations are free of errors in
formulation of wall boundary conditions and to evaluate the relative
performances of competing numerical algorithms. Because the solution
pertains to flows driven by a surface thermal forcing, one of its main
applications may be for testing the no-slip, impermeable wall boundary
conditions for the pressure Poisson equation. Examples of such tests are
presented. |
