Experimental and numerical studies are performed on steady and unsteady lid-driven cavity flow for laminar flow regime. In the experiments, a PIV and an LDA were employed to measure the global and local velocities, respectively inside a cavity of AR 1.0. The velocity vector plots and streamline plots which represent unsteady circulation patterns are obtained using the PIV. The steady local velocities measured with LDA are then used to calibrate the PIV measurements. The numerical study is performed using a commercial CFD solver. For turbulent flow simulation RANS equations with K-Epsilon closure model were used. From the PIV calibration study, it can be observed that the characteristic of the horizontal velocity profile measured using PIV and predicted by CFD solver agrees with each other however both overestimates the ones given by LDA. In unsteady simulations, the lid acceleration was found to influence the development and movement of circulation centers.
