STEADY-STATE POOL BOILING HEAT TRANSFER TO SATURATED LIQUID HELIUM AT ATMOSPHERIC PRESSURE.

Type of article: Article

Summary

IT WAS FOUND THAT THE NUCLEATE BOILING HEAT TRANSFER INCREASED AS THE SURFACE ROUGHNESS INCREASED. FURTHERMORE, INCREASING THE SURFACE INCLINATION INCREASED THE NUCLEATE BOILING HEAT TRANSFER IN THE LOW HEAT FLUX REGION. THE TWO-PHASE BOUNDARY-LAYER ANALYSIS OF SATURATED FILM BOILING WAS FOUND TO UNDERESTIMATE THE HEAT TRANSFER COEFFICIENT, BUT BY MODIFYING THE HEAT TRANSFER LENGTH, THE EFFECTS OF SURFACE SUPERHEAT AND THE SURFACE INCLINATION COULD BE CORRECTLY PREDICTED. THE SURFACE ROUGHNESS DOES NOT AFFECT THE CRITICAL HEAT FLUX, BUT THE SURFACE ORIENTATION HAS A PRONOUNCED EFFECT ON IT.
