【Abstract】 For a slot jet impinging on a rotating cylinder wall, the influences of the distance between nozzle and cylinder, the width of nozzle, the cylinder diameter, and the rotational parameters on heat transfer are investigated. An experimental relationship is obtained. There are no obvious effects on the average heat transfer coefficients as the rotating Reynolds number increases, but the distribution of the local coefficients will be changed.更多还原
