对两个同轴旋转圆盘径向向外流动的空气传热速率进行了实验研究。得到了固定圆盘时5种质量流量和旋转圆盘时4种质量流量和5种转速下的换热数据。在最高转速（600 rmp）下，与未旋转的平均努塞尔数相比，旋转磁盘的平均努塞尔数略有下降，但在较低转速下，没有观察到一致的趋势。旋转前后平均努塞尔数分别为Nu= 0.0529 re0.71，局部努塞尔数为Nu= 0.124 Re0.608。
An experimental study of heat transfer rates to air flowing radially outward between two coaxial, corotating disks was made. Heat transfer data were obtained for five mass flow rates with stationary disks and four mass flow rates and five rotational speeds with rotating disks. Rotation of the disks slightly decreased the average Nusselt numbers compared with the average Nusselt numbers without rotation at the highest speed of rotation (600 rmp), but at lower speeds no consistent trends were observed. The average Nusselt numbers, with and without rotation, can be related asNu= 0.0529 Re0.71and the local Nusselt number as Nu = 0.124 Re0.608.
