Description
Summary:In this paper, first, the principle, structures, operations, and performances of the cryogenic wind tunnel are described. By changing the pressure, temperature and velocity of gas a high Reynolds number flow (5×104<Re<107) can be obtained. From the research results, a high Reynolds number flow with comparatively low power, LN2 consumptions was attained. It was with Mach number independent of each other.
