A SENSITIVITY STUDY OF THE EFFECTS OF EVAPORATION/CONDENSATION ACCOMMODATION COEFFICIENTS ON TRANSIENT HEAT PIPE MODELLING.

Author(s) : HALL M. L., DOSTER J. M.

Type of article: Article

Summary

THE DYNAMIC BEHAVIOUR OF LIQUID METAL HEAT PIPE MODELS IS STRONGLY INFLUENCED BY THE CHOICE OF EVAPORATION AND CONDENSATION MODELLING TECHNIQUES. CLASSIC KINETIC THEORY DESCRIPTIONS OF THE EVAPORATION AND CONDENSATION PROCESSES ARE OFTEN INADEQUATE FOR REAL SITUATIONS. THE COMPLEX GEOMETRIES AND FLOW FIELDS FOUND IN PROPOSED HEAT PIPE SYSTEMS CAUSE CONSIDERABLE DEVIATION FROM THE CLASSICAL MODELS. THE RU CODE, WHICH HAS BEEN DESCRIBED IN PREVIOUS WORKS, WAS DEVELOPED TO MODEL TRANSIENT LIQUID METAL HEAT PIPE BEHAVIOUR FROM FROZEN STARTUP CONDITIONS TO STEADY STATE FULL POWER OPERATION.
