Abstract

The flow in a periodically-driven cavity is studied experimentally using Particle Image Velocimetry (PIV) and the results are compared with Computational Fluid Dynamics (CFD) simulations. The experiments are carried out in a cuboid of 0.1x 0.1m x 0.02 m size with glycerol as the fluid. Measurements are carried out at various amplitudes and frequencies of lid motion. The planar velocity measurements are made at three different z-planes and x-planes. It is found that the temporal variations of x-, y- and z-components of velocities of the flow are periodic, with the imposed plate frequency as the dominant frequency. Computation using FLUENT package show close agreement with experimental data. The effect of width of the cavity is studied using CFD simulations. Subsequently flow patterns in cases with different widths show similarities when a modified Reynolds number is used.
