概要

論文の詳細を見る
An experimental study was made for torque characteristics of a slitted rotating disk enclosed in a cylindrical housing. Measurements were carried out when the disk was positioned at and off the center of the housing clearance, and comparison was made between a slitted and a non slitted disk. The slits in the disk had little effect on the performance for a Reynolds number less than l000 except for a slight decrease in torque. At larger Reynolds numbers, however, slits act as impeller passages of a centrifugal pump, and this enables more torque to be transmitted. The torque for a disk which is set at off the center of clearance depends only on the ratio of upper and lower clearances for Reynolds numbers below 1000, but for larger Reynolds numbers it depends on the sum of the clearances irrespective of the difference between upper and lower clearance.
