Hi all,
Recently I've tried to use OpenFOAM 3.0EX Density based turbo solver to carry out the supercritical CO_2 radial turbine simulation. However, when I try to operate the simulation, I've got many questions related to that.
--> The second step of my simulation has a big temperature drop, from 833.15K massively to 8.2K;
--> I've no idea how to implementation the Janaf specific heat for CO_2 into the thermoPhisicalPropeties.

I've attached my setting files and boundry, system files at this threads.

Thanks for your help!!!
