Two-Dimensional Numerical Investigation of Oscillatory Shear-Driven Flows in Slip Flow Regime between Two Microscale Concentric Cylinders

Abstract:

Shear-driven flows in microscopic systems are of great interest among scientists and engineers nowadays. In this document, shear-driven flow between two concentric micro-cylinders was studied in two different configurations in which the second one includes a general form of oscillation of the walls. In both configurations, effects of slip condition on velocity and shear rate profiles and torque required to rotate the system are investigated in comparison to no-slip conditions. For oscillatory configuration, in addition to studying aforementioned effects, the effects of variation in frequency values of the oscillating walls on stokes layer depth and phase angles are studied.
