SYMPTOM:
The solver can give obviously incorrect values for heat transfer in multiphase and particle transport calculations, as the latent heat is wrongly calculated.
PROBLEM:
The values for reference enthalpy and reference entropy of H2Ol are incorrectly specified to be consistent with values for H2O where the specific heat is specified as a NASA polynomial. As well as some of the default materials files, this also applies to the evaporating_drops and spray_dryer templates.
WORKAROUND: If such a multiphase or particle transport calculation is undertaken, set the reference enthalpy and perhaps reference entropy to more appropraite values. FIXED IN: ANSYS CFX Release 11.0 Service Pack 1. |
