Abstract |
This study investigate experimentally the effect of fin height, thickness, and clearance on the boiling heat transfer. The heat surfaces having copper fin array is tested for pool boiling. The gas-liquid exchange interference is investigated based on fin array clearance. These test results can be applied to the design of tube bundle system. The fin height of 2 mm is found to be effective. Effects of heat transfer promotion reaches the highest level when the fin clearance is 0.5 mm. Also, heat flux is increased when the fin thickness is smaller. But 0.2 mm fin thickness is highly recommended. |
