For the purpose of promoting Heat Transfer, the experiment which the heating surface was moving reciprocally in the still air was carried out. The heating surface was a vertical cylinder made of copper tube. A cartridge heater was disposed in it. The cylinder was mounted on the table of a slider. Also, the cylinder was moved on the cross direction to the axis of the cylinder. The strokes were 250, 500, 750 and 1000mmm. These acceleration and deceleration were 2m/s^2. Each constant speeds were 300, 600, 900 and 1200mm/s. The experiments were carried out on the steady state. The temperatures on the cylinder were measured by seven thermocouples deposited at interval of 30 degrees along the cylinder surface. In the consequence of this study, these temperature distributions for the reciprocal movement were confirmed. The heat transfer characteristics were influenced greatly by the speed of the motion. Also, the accelerations and the deceleration influenced upon the performances.
