Abstract

Flows between corotating flat multidisks were studied with two methods, flow visualization and numerical simulation. Flow visualization was performed for Reynolds number from 600 to 2000 and dimensionless spacing H/R of two disks from 0.1 to 0.4. When angular velocities of multidisks were changed to faster, slower or reverse rotation, streaklines of flow fields were observed in the laser light sheet. For the reverse of rotation, unsteady behavior of secondary flows in the meridian plane of two disks showed that tornado effects appeared on the disk in a short time, and then steady secondary flows of constant rotation were formed. Incompressible axisymmetric viscous flows between the multidisks were analyzed through the finite element method-the SMAC method. Growth process of the tornado effects in flow fields was numerically represented in detail. Results from numerical simulation corresponded to that of flow visualization.
