modelGungorWinterton87
The simplified Gungor-Winterton correlation for turbulent two phase flow
Extends from BaseClasses.PartialTwoPhaseCorrelation (Base class for two phase heat transfer correlations).
Information
The model GungorWinterton87 extends the partial model PartialTwoPhaseCorrelation and calculates the heat transfer coefficient based on the GungerWinterton correlation.
