CFD simulations of the 2D lid-driven square cavity flow are performed for a wide range of Reynolds numbers. The two-dimensional square lid driven cavity can be achieved by steady motion of the upper walls. This paper mainly focuses on flow and mixing characteristics of fluids in a Lid driven square cavity by steady motion of both upper and bottom plate. This aims at simulating square 2-D Lid driven cavity flow at different Reynolds number. Also, simulations can be carried out by introducing a solid object (i.e. square block) at different positions in the cavity and streamline patterns can be compared with above case and its mixing characteristics has been studied. The comprehensive features and variations of flow patterns of the flow field under various operating conditions can be computed. The cavity flow is studied as it is a flow which shows very clearly the important aspects of mixing behavior in a creeping flow. The mixing rates can be analyzed in terms of the flow patterns and tracer dynamics. Using CFD, the study of mixing characteristics of fluids based on cavity flow becomes easier and more economic than with the use of experiments. Mixing is relevant where Reynolds number is high and diffusion rate is high.
