Hi everyone!

I want to calculate a bubble with compressibleInterFoam with version 2.2.1.
In the TermoPhysicalPropertiesair or ""water you can specify the equationOfState that is used. However it seems that adiabaticPerfectFluid (provided with the source code) is not a valid option. If I type "bla" into the entry and look at the list in the error message, only incompressiblePerfectFluid, PerfectGas, PerfectFluid, icoPolynomial are shown as valid. Is this an error in the code or am I wrong? I would like to use the equation from adiabaticPerfectFluid.

Thanks!

Hi,
did you find solution to this?

Yes, it was my Master-Thesis. But I changed to OpenFoam extend 3.1. And changed the solver to my needs. Never worked with commercial OpenFoam anymore since then.

Thank you for your reply. May I ask you for a case where you used the adiabaticPerfectFluid model? It would surely save me a few hours.

Sorry, as I said, I used openfoam extend, which doesn't have this kind of structure. I didn't solve it with openfoam 221. What I did was taking the compressibleInterFoam from openfoam extend and then modified the equations of state p(rho) such that in pEqn.H and createFields.H they resemble an adiabatic one for the gas and the compressible Tait Equation for the liquid. See my article http://www.sciencedirect.com/science...45793015003795

Regards,
Max

For me it is possible to use adiabaticPerfectFluid with standard OpenFoam version (2.4.0), which is the same as Tait equation I think.
