Abstract: Flow in a three-dimensional lid-driven cavity (LDC) is studied using the lattice Boltzmann method (LBM) for various values of Reynolds number (Re). The 1000 Re flow is simulated on two grid sizes: viz. 2253and 3013. We further compute the Richardson extrapolated flow profiles. Our results agree quantitatively with the spectral simulation results. We observe a steady to oscillatory transition of the flow in the range of Re [1900, 2000].
