Type of article: Article

Summary

A NOVEL GRADIENT METHOD WAS DEVELOPED BASED ON MEASUREMENT OF THE WALL INTERNAL AND EXTERNAL SURFACE-TEMPERATURE DISTRIBUTIONS. RUNS WERE MADE IN THE RANGE OF REYNOLDS NUMBERS WHERE THE FLOW IS TURBULENT UPON ENTERING THE COIL, BUT LAMINAR DOWNSTREAM WHERE SECONDARY FLOW DEVELOPS. THE RESULTS INDICATE A RAPID TRANSITION TO LAMINAR FLOW AND ARE IN SATISFACTORY AGREEMENT WITH A NUMERICAL SOLUTION FOR FULLY DEVELOPED HEAT TRANSFER.
