INTO A CLOSED CAVITY

The exact solution of the equations of incompressible-fluid 
dynamics which is interpreted as jet flow in a closed cavity is found. 
The boundary-layer equations on the cavity walls are obtained and 
the problem of heat exchange between the jet and the walls is solved. 
It is shown that as the jet source moves away from the cavity bottom, 
the Nusselt number decreases exponentially.
