Abstract
A two dimensional incompressible flow past a rotating circular cylinder near a plane wall at is investigated by using the lattice Boltzmann equation (LBE). The effects of the gap between the cylinder and the wall, and tangential speed of the cylinder on the frequency of vortex shedding, and the lift and drag forces on the cylinder are quantified together with the flow patterns. With a fixed tangential speed of the cylinder, the flow behavior strongly depends on the normalized cylinder-wall gap , where
