CONDENSATION OF FLOWING VAPOUR ON A HORIZONTAL TUBE: NUMERICAL ANALYSIS AS A CONJUGATE HEAT TRANSFER PROBLEM.

Author(s) : HONDA H., FUJII T.

Type of article: Article

Summary

CONDENSATION OF FLOWING VAPOUR ON A HORIZONTAL TUBE IS NUMERICALLY ANALYZED UNDER GIVEN CONDITIONS OF VAPOUR AND COOLANT. SOME APPROXIMATIONS ARE INTRODUCED FOR THE DETERMINATION OF SHEAR STRESS AT THE VAPOUR-LIQUID INTERFACE. THE CONJUGATION OF THE TWO-PHASE BOUNDARY LAYER EQUATIONS AND THE HEAT CONDUCTION EQUATION WITHIN THE TUBE WALL IS ACHIEVED BY USING AN ITERATIVE SCHEME AT THE OUTER SURFACE. THE SOLUTION REVEALS THE EFFECTS OF VAPOUR VELOCITY, TUBE MATERIAL, HEAT TRANSFER OF COOLANT SIDE, UPON DISTRIBUTIONS OF TEMPERATURE, HEAT FLUX DENSITY, AND NUSSELT NUMBER AT THE OUTER TUBE SURFACE. THE SOLUTION COMPARED WELL WITH AVAILABLE EXPERIMENTAL RESULTS.
