THE EFFECT OF SURFACE TENSION VARIATION ON FILM-WISE CONDENSATION AND HEAT TRANSFER ON A CYLINDER IN CROSSFLOW.

Author(s) : JACOBI A. M., GOLDSCHMIDT V. W.

Type of article: Article

Summary

THE EARLIER ANALYSES OF NUSSELT AND ROSE WHICH PREDICT HEAT TRANSFER IN A CONDENSING CROSSFLOW OVER AN INFINITE CYLINDER ARE EXTENDED TO ACCOUNT FOR THE MARANGONI EFFECT. THE INFLUENCE ONLOCAL HEAT TRANSFER IS NOTABLE FOR CASES OF HIGH VAPOUR VELOCITY. THE AVERAGE VALUES OF HEAT TRANSFER ARE NOT AS EASILY COMPARED WITH EXPERIMENTAL RESULTS DUE TO A SINGULARITY IN THE SOLUTION CORRESPONDING TO THE RAPID THICKENING OF THE CONDENSATE LAYER.
