NF-6 wind tunnel is the first pressurized continuous transonic cryogenic two dimensional wind tunnel in China. The performance of the NF-6 wind tunnel depend up on axial compressor to large extent.

Transonic tube wind tunnel flows over supercritical airfoils with slots on both upper and lower walls have been simulated by using compressible unsteady two dimensional Navier-Stokes equations.

This paper presents an investigation on the side wall effect in two -dimensional transonic wind tunnel with sidewall boundary layer suction around the model.
