Natural Convection:
 

 

 

 

This case is an example of buoyancy-driven convection within a simple rectangular cavity. The two side walls of the cavity are held at different temperatures (the left side 45.8K hotter than the right), with the lower and upper walls assumed to be fully insulated. The force due to gravity is specified as -9.8ms-2, acting in the verical (y) direction. The gas is initially assumed to be quiescent and the equations are solved using the default cubic k-epsilon turbulence model in CFD++. Here, the data are compared against the experiments of Cheesewright et al[1].
