Riemann problem with two strong rarefactin waves
 

Dear Fluent users!

I am very interesting how Fluent code can solve 1D Riemann problem with two strong rarefactin waves: Heat ratio = 1.4; Left conditions: Density=1.4, Pressure=1, Velocity=-2.5; Right conditions: Density=1.4, Pressure=1, Velocity=2.5; I would be appreciate if anybody send me e-mail with profiles of density and pressure. Please, use the following conditions: Courant number 0.9, uniform grid 1000 cells or more, number of time iterations - approx. 500-1000.

Thank you. Alexey

(1). I know that there is a density-based module in Fluent, and I have seen messages posted related to the supersonic flow applications. (2). So, I think someone out there can model it, even though the code is 3-D.
