The three-dimensional incompressible single lid-driven cavity flow problem is solved by using a combined compact difference (CCD) scheme. The CCD scheme proposed by the authors has high accuracy and resolution. This difference scheme is utilized for solving the Poisson equation for the pressure as well as calculating spatial derivatives in the incompressible Navier-Stokes equation. The ADI method is employed for solving the Poisson equation. Flow in cavities with spanwise aspect ratio (SAR) equal to 1, 3, 4, 5 and 6.55 are calculated. The cellular structure is observed nearby the upstream wall for SAR=6.55.
