Please see the attached gambit file.
In fluent the conditions are "coupled, axixymmetric, 2D, unstedy, 2nd order" etc. You have to use the pressure ration as shown in 3.2 in the attached paper.(1.27778, 1.55556 etc), pressure unit will be atm [url removed, login to view] solution should be convesed . time step , 0.0000004. internal iteration 3.
There must be lambda shock in the diverging section as shown in the attached figure (in unsteady condition). Take 15 points at the divergent section to see the preesure fluctuation over flow time.
You have to send me case & data file of fluent.
You must use fluent 6.2.16. Using this verstion is mandatory.
The result shoud be same as in the attached paper.
Waiting for your reply.
