Summary

THE NUMERICAL RESULTS ARE OBTAINED BY USING THE IMPLICIT NON-ITERATIVE BEAM-WARMING FINITE DIFFERENCE METHOD. THE MODEL IS TESTED FOR SIMULATED HEAT PIPE VAPOUR FLOW AND ACTUAL VAPOUR FLOW IN CYLINDRICAL HEAT PIPES. A GOOD COMPARISON OF THE PRESENT TRANSIENT RESULTS WITH THE PREVIOUS RESULTS OF A TWO-DIMENSIONAL NUMERICAL MODEL IS ACHIEVED AND THE STEADY STATE RESULTS ARE IN AGREEMENT WITH THE EXISTING EXPERIMENTALDT. THE TRANSIENT BEHAVIOUR OF THE VAPOUR FLOW UNDER SUBSONIC, SONIC, AND SUPERSONIC SPEEDS AS WELL AS HIGH MASS FLOW RATES ARE SUCCESSFULLY PREDICTED.
