Freon-14 as a working medium in wind tunnels for modeling hypersonic air flows
Abstract
The thermodynamic and kinetic properties of Freon-14, a gas characterized by a low adiabat and well suited to the modelling of real gas effects in wind tunnels, are examined. It is shown that flows that are free from condensation and closely resemble equilibrium flows can be obtained over a sufficiently wide range of wind tunnel regimes and model sizes. Viscosity coefficients of Freon-14 are presented.
