Notes:
In order to improve the heat transfer efficiency, the fins are commonly used in theindustrial boiler in Japan. In actual application, the thermal fatigue due to the cyclic change oftemperature usually occurs in the fins. The thermal fatigue tests were carried out by using thethermal fatigue apparatus designed. The designed testing apparatus can apply thermal load to the finby giving heating and cooling alternatively. The fatigue cracks can be observed in the vicinity of thetoe in the thermal fatigue test. The heat transfer coefficient and the thermal stress were calculatedby using Finite Element Analysis (FEA) method. The fatigue experiments of the fins were alsoconducted using electro-hydraulic servo fatigue test machine in the laboratory. The results ofthermal fatigue experiments were discussed by comparing with those of the mechanical fatigueexperiments
