Calculations of the pressure drop in the natural circulation boiler evaporator

Calculations of the pressure drop in the natural circulation boiler evaporator

The paper presents different models used to determine pressure losses in two-phase flows: the homogeneous model, the Lockhart-Martinelli, the Friedel and the Chisholm phase-slip models and the Martinelli-Nelson graphical method. The pressure losses are calculated for the evaporator of an OP-210 boil...
