What is "R" in compressibleTwoPhaseEulerFoam bubble column tutorial?
Hello
I am trying to decipher the input files for the two-phase example of a bubble column, in order to be able to modify them for my own application. I understand all the 'transportPropoerties' info except for "R": phase1 { rho 1; rho0 0; R 287; Cp 1007; nu 1.589e-05; kappa 2.63e-2; diameterModel isothermal; isothermalCoeffs { d0 3e-3; p0 1e5; } } Any ideas? Thanks!! |
R is clearly the universal gas constant for air.
|
Thanks immortality. I thought it was something like that, but I'm not sure why the value of R for the second phase (water) is set to be 1e10. Is this a randomly large number, or does it have any meaning?
|
your welcome.where it has defined for water?
------------ I think because its not gas it has given a high value so that its increase in volume due to heat addition in constant pressure is small then specific heat is high. |
In file transportProperties:
phase2 //liquid { rho 1027; rho0 1027; R 1e10; Cp 4195; nu 3e-7; kappa 0.668; diameterModel constant; constantCoeffs { d 1e-4; } } |
i updated the above post if you have seen and also thank you for reputation.
Could you find a formula of R that can argue for liquids? |
i need to simulate the sperical bubble growth
can the compressibleTwoPhaseEulerFoam used for the simulation of the growth of a spherical bubble? thanking you in advance.
