jet flow simulations
I'm looking for tips to improve my convergence time to a steady state solution using CFX TASCFLOW, to model the flow of a supersonic gas jet (2d asisymmetric) (underxpanded or over expanded jet) issuing from a nozzle into ambient conditions.
The flow field contains widely varying timescales at different regions of the flow fild. The use of ETFACT (local time step factor) has been discouraged.
