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 { version 2.0; format ascii; class dictionary; object thermophysicalProperties.liquid; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // thermoType { type heRhoThermo; mixture pureMixture; transport const; thermo hConst; equationOfState rhoConst;//perfectFluid;// specie specie; energy sensibleEnthalpy;//sensibleInternalEnergy; } mixture { specie { molWeight 18.0153; } equationOfState { R 3000; rho0 868; rho 868; //rhoCoeffs<8> ( 1513.93 -1.3688 0 0 0 0 0 0 ); // rho = a + bT } thermodynamics { Sf 0; Hf 0; // CpCoeffs<8> ( 654.38 8.1036 0 0 0 0 0 0 ) Cp 4954.1; // Cv 3136.7; Tref 530.59; Href 1122200; //Eref 1116500; } transport { mu 0.00010293; Pr 0.8377; } } FoamFile { version 2.0; format ascii; class dictionary; object thermophysicalProperties.gas; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // thermoType { type heRhoThermo; mixture pureMixture; transport const; thermo hConst; equationOfState perfectGas; specie specie; energy sensibleEnthalpy;// sensibleInternalEnergy; } mixture { specie { molWeight 18.0153; } equationOfState { R 1695; rho 22.697; } thermodynamics { Hf 0; Cp 4227; // Cv 2532; Tref 530.59; Href 2797900; //Eref 2599700; } transport { mu 1.771e-5; Pr 1.423; } } // ****************************** |
