Type of article: Article

Summary

THE RESULTS OF AN EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER IN THE CLOSED TUBE THERMOSIPHON UNDER LAMINAR CONDITIONS ARE PRESENTED. ATTENTION IS FOCUSED ON THE EFFECT OF TUBE GEOMETRY WHEN THE RAYLEIGH NUMBER IS LOW ENOUGH TO CREATE BOUNDARY LAYER, TRANSITIONAL AND IMPEDED FLOWS. THE DATA SHOW THAT THE LENGTH-DIAMETER RATIO AND HEATED-COOLED LENGTH RATIO BOTH HAVE A MONOTONIC EFFECT ON THE HEAT TRANSFER RATE, THE FORMER BEING THE GREATER. RESULTS ARE PRESENTED FOR BOTH AIR AND WATER.
