LAMINAR RECTANGULAR CAVITY FLOW WITH HEAT TRANSFER
2-dimensional (x-y), Cartesian, steady, elliptic
This demonstration shows the influence of the Prandtl number of
the fluid on the temperature distribution within a square cold-
walled cavity with a moving heated top wall.
You will be asked whether you wish to change the Reynolds number
or the aspect ratio of the cavity.
