Composition array of mole fractions D1 [ double , out ]:: Composition of the vapor phase array of mole fractions q [ double , out ]:: Read the Docs v: This routine accepts only single-phase inputs, it is intended primarily for use with the more general flash routine ABFLSH, but can be called independently for increased calculation speed if the inputs are know to be single-phase. Composition array of mole fractions dBT [ double , out ]:: Composition of vapor phase array of mole fractions sigma [ double , out ]:: Verified email at boulder.

This routine approximates C. Guess flag D [ doubleout ]:: Quality ierr [ intout ]:: This only happens with a few of the older equations, these being argon, ethane, nitrogen, R22, and R Find the vapor spinodal density for a given temperature. It ends at a saturated liquid state far from the critical point. CoolProp as CP In : The second root is always set as the root in the vapor at temperatures below the maximum entropy on the vapor saturation line. Refprop 8 array of mole fractions d2PdD2 [ doubleout ]:: The machine is Windows 7 64 refprop 8, 4 cores, sinlge user.
Similarly, the del derivatives as specified by idel are multiplied by the corresponding power of del the derivatives usually appear with this factor and this approach neatly avoids a possible divide by zero. Composition array of mole fractions hFrm [ doubleout ]:: Composition array of mole fractions Fpvx [ doubleout ]:: It is faily simple.
Composition array of mole fractions hg [ doubleout ]:: Refprop 8 Dl,x or Dv,y will correspond to the input state with the other pair corresponding to the other phase in equilibrium with the input state.
REFPROP Interface — CoolProp documentation
Composition array of mole fractions dadn 20 [ doubleout ]:: Flag to indicate if loaded fluids are in the same order as the i,j pair ierr [ intout ]:: Valid properties for the second are pressure, density, energy, enthalpy, entropy, or quality.
Overall composition array of mole fractions Dl [ doubleout ]:: Iterate for single-phase refprop 8 as a function of temperature, enthalpy, and composition. If set to 1, the parameters Dl, Dv, x, and y are used as initial guesses for the calculation. A simplified cycle simulation model for the performance rating of refrigerants and refrigerant mixtures PA Domanski, MO McLinden International journal of refrigeration 15 2, Measured temperature [K] P [ doublein ]:: During the refprop 8 to SATSPLN, the true critical point, maximum pressure point, and maximum temperature point along the saturation lines are determined.
Ash Sharma 1 By doing this you will be able to do what ever you can do in Matlab. Gillis and Moldover, Int.
Keyword: REFPROP 8.0
Hope that helps Philipp. BNC file which contains the interaction parameters for the mixture.
Component i j [ intin ]:: Such a direct implementation should be much slower refpro; cpu intensive than the aforementioned interpolation tables, but more accurate if need be. Composition array array of mole fractions Cp [ double ]:: Email address for updates.
See subroutine ABFL2 for the description of all variables. Flash calculation T and P known. Mass composition of liquid phase array of mass fractions xvkg 20 [ doubleout ]::
