| Abstract: | An investigation on steam water two-phase flow instability in U-shaped tubes was con-ducted.Pressure-drop-type instability and the influences of pressure,mass velocity,inletsubcooling, and heat flux on it were studied and discussed in detail.Based on the experimen-tal results and dimensionless analysis,an empirical correlation to predict the critical heat fluxwhen the pressure-drop-type instability takes place is given,The test results and the correla-tion can be used in the design of heat transfer apparatus with U-shaped tubes. |
