Abstract
This is a report of a study of enclosed rotating disks with radial outward throughflow superposed on the fluid motion induced by the disk. The report presents information on the flow mechanics in the axial clearance space between the disk and stationary endwall including mean steady velocity distributions and unsteady periodicities. Also included are data on the interactions between fluid and boundaries as evidenced by torque transmission (disk friction) and by radial pressure gradients. A theoretical analysis is presented to predict the steady state values of torque and pressure distribution and is compared with experimental results. Quantitative measurements of unsteadiness and periodicities which result under some conditions are analyzed and compared with previous smoke visualization data.
