Abstract

Numerical simulations of fingering stabilities in a miscible rotating Hele-Shaw flow are presented. Unstable mechanism is resulted from the centrifugal force if the more viscous fluid, in general heavier and viscous stable, is placed at the rotating origin. The interfacial stabilities are determined by the competition of unstable centrifugal force and stable viscous effects. The centrifugal fingerings differ from the radial flow in two facts. More pronounced fingerings are found at later time with multi-layer fingering fronts.
