%X The model of the stationary and rotating isolated wheels is studied with numerical methods under fixed ground boundary conditions. Based on the k-s two-equation high Reynolds number model, the 3D steady incompressible N-S equations are solved numerically with the CFD software STAR-CD. The drag coefficients of three different breadth stationary and rotating isolated wheels are calculated in an appropriate computational domain, then the relationship between breadth, velocity of the flow and drag coefficient is discussed. In addition, from the calculated results and test results, the paper also discusses the velocity field and the pressure field around the wheels.
