Abstract�� High temperature chemical non-equilibrium phenomena have a great effect on the flow field around a reentry vehicle. A three dimensional Navier-Stokes equations were solved by implicit finite volume NND scheme. Both ideal gas viscous flow and chemical non-equilibrium flow were calculated for a sphere-cone at a small attack angle. The results of the two flows were compared and the effect of chemical non-equilibrium was analyzed. The result is in good agreement with the reference paper. That proves that our method and programs are effective and practical.
