Comparison between AEDIF3D and the expermental data of Moyce and Martin 1952
2D Mesh 101x101 vertices, 3D Mesh 101x101x3 vertices

Rhomax is the total density of the mixture. This is a hydrostatic flow with the gravity force being in the top to bottom direction. If the initial profiles were the exact solutions the calculation would not change at the numerical solution advances in time. However for this calculation, the initial profiles were taken as constant density and pressure with the velocities set to zero. Thus the initial potential energy is greater than the steady-state energy so the computed solutions develop an oscillatory motion about the steady state. As the Euler equations are being solved, there is no physical dissipation to eliminate the excess energy in the initial profiles (only a small dissipation introduced by the numerical scheme) and therefore the computed solutions remains oscillatory in time. The third-order time difference scheme of Shu was used. The spatial scheme is second-order accurate. The object of this comparison is to show that the solutions between the 2D and 3D codes agree.
