Fluid flow in a cavity driven by an oscillating lid-A simulation by lattice Boltzmann method

► A BGK LBM model is developed to simulate the fluid flow phenomenon in a cavity driven by an oscillating lid. ► The effect of Reynolds number and frequency of oscillation on temporal variation of fluid flow has been studied. ► An increase in Reynolds number promotes the development of vortices within the cavity. ► The number of vortices diminishes as the frequency of oscillation increases. ► Phase diagram shows the periodicity of the system.
