High-speed gas flow
I'm just getting familiar with DSPH and would like to ask for some direction on how to simulate high pressure and high speed gas flow. I have adjusted the viscosity, density parameters under the <constantsdef> section but not sure how to represent high pressure expanding gas.
My problem is quite simple; I am looking to find out the pressure variation in air due to a sphere of high pressure gas expanding quickly over a flat surface. I have it done in OpenFOAM and would like to compare the findings with DSPH.
(as in high pressure: several Mach....so in essence an exploding bubble of air)
Any help is appreciated
