Hi guys,
I am using rhoSimpleFoam and cannot use the linear EoS even if it is defined in the thermophysical properties. I want to investigate the density change by changing just the pressure, not the temperature. The linear EoS condition may give a reasonable solution for my case because the fluid is a liquid.. I got the problem there --> FOAM FATAL IO ERROR: (openfoam-2312) Unknown fluidThermo type Valid fluidThermo types : my file FoamFile { version 2.0; format ascii; class dictionary; location "constant"; object thermophysicalProperties; } thermoType { type heRhoThermo; mixture pureMixture; transport const; thermo hConst; equationOfState linear; specie specie; energy sensibleInternalEnergy; } mixture { specie { nMoles 1; molWeight 100; // Example molar weight for oil } equationOfState { psi 670e-12; // Compressibility coefficient rho0 860; // Reference density } thermodynamics { Cp 2500; // Specific heat capacity Hf 0; // Formation enthalpy } transport { mu 0.03999; // Viscosity Pr 0.7; // Prandtl number } } |
