THE INFLUENCE OF WALL VIBRATION AND STREAM TURBULENCE ON THE HEAT TRANSFER ON CYLINDERS IN CROSSFLOW.

Author(s) : CURKO T.

Summary

THIS REPORT CONSIDERS THE RESULTS OF THE EXPERIMENTAL EXAMINATION OF THE HEAT TRANSFER FROM A VIBRATING HORIZONTAL CYLINDER TO AIR IN CROSSFLOW. THE PARAMETERS EXAMINED ARE: FREQUENCY, AMPLITUDE, WALL TEMPERATURE AND AIR FLOW VELOCIT THE FREE AIR STREAM TURBULENCE LEVEL WAS 1.1%. THE ANALYSIS OF RESULTS SHOWS THAT THE VIBRATION VELOCITY IS THE HEAT TRANSFER PARAMETER AND THAT THE AVERAGE HEAT EXCHANGE INTENSITY IS INCREASED BY VIBRATIONS BY UP TO 25%.
