Type of article: Article

Summary

THE MODEL IS SIMPLIFIED AND SOLVED NUMERICALLY. THE TWO-DIMENSIONAL TRANSIENT MODEL FOR THE WALL AND WICK IS COUPLED WITH THE ONE-DIMENSIONAL TRANSIENT MODEL FOR THE VAPOUR FLOW WHEN VAPORIZATION AND CONDENSATION OCCUR AT THE INTERFACE. A PARAMETRIC STUDY IS PERFORMED TO EXAMINE THE EFFECT OF THE BOUNDARY SPECIFICATION AT THE SURFACE OF THE OUTER WALL ON THE SUCCESSFUL START-UP FROMTHE FROZEN STATE. FOR SUCCESSFUL START-UP, THE BOUNDARY SPECIFICATION AT THE OUTER WALL SURFACE MUST MELT THE WORKING SUBSTANCE IN THE CONDENSER BEFORE DRYOUT TAKES PLACE IN THE EVAPORATOR.
