ShareSummary
THE HEAT TRANSFER IN THE HEATING AND COOLING ZONES OF A CLOSED THERMOSYPHON TUBE HAS BEEN STUDIED EXPERIMENTALLY. R115 WAS USED AS A WORKING FLUID. ACCORDING TO THE CRITICAL SPECIFIC VOLUME, THE QUANTITY OF THE FLUID WAS DETERMINED. DEPENDING ON PRESSURE, THERE ARE THREE REGIMES OF BOILING: NUCLEATE BOILING, NUCLEATE BOILING IN A TRANSITION REGIME AND FILM BOILING. IN THE THERMOSYPHON, THERE EXIST LAMINAR AND TURBULENT FILM CONDENSATION, RESPECTIVELY. COMBINED HEAT TRANSFER IN THE HEATING AND COOLING ZONES RENDERS AN OVERALL PERFORMANCE WITH OPTIMAL CONDITIONS AT AN INCLINATION ANGLE OF ABOUT 40 DEG AND A SMALL HEAT FLOW RATE AND PRESSURES.
