Flow and thermal fields in channels between corotating disks

Flow and thermal fields in disk packs are analyzed numerically. These flows are a subset of enclosed rotating cavity flows in which the disks are rotating with the same angular velocity and contained within a fixed cylindrical shroud. The axisymmetric model under consideration consists of a pair of corotating disks with mid-line symmetry. The corotating disks are assumed to be fully shrouded. Computed velocity and temperature fields in the gap between corotating disks are given for a 5.25-in. disk geometry drive. Estimates of disk windage for corotating disks were found to be 30 to 40% of those obtained for a rotor/stator geometry.<>
