SHY22 is on a distinguished road
Hi everyone!
I m a newer with the openfoam and I want to simulate the Bartolomej subcooled boiling using reactingTwoPhaseEulerFoam.
There are so many questions with me.
first of all:How to set the thermophysicalProperties?
According to a literature by Qin Hao: set the physical properties of the gas to be saturated, and the physical properties of the fluid change with temperature. I don't know how this should be set up, can you please give me some advice or any information to refer to?

FoamFile

class dictionary;
object thermophysicalProperties.liquid;

thermoType
{
type heRhoThermo;
mixture pureMixture;
transport const;
thermo hConst;
equationOfState rhoConst;//perfectFluid;//
specie specie;
energy sensibleEnthalpy;//sensibleInternalEnergy;
}

mixture
{
specie

rho0 868;
rho 868;
//rhoCoeffs<8> ( 1513.93 -1.3688 0 0 0 0 0 0 ); // rho = a + bT

}
