An analytical study of a technique for achieving high Reynolds number similarity in a wind tunnel was conducted. The technique under consideration required that the momentum boundary layer be immersed in a layer of cryogenically cooled gas so that boundary layer development would be determined by the low temperature fluid properties. The experimental technique was shown to be theoretically feasible, with effective Reynolds number increased by as much as a factor of seven or eight, provided that sufficiently high mass rates of flow of cool gas could be provided.
