Abstract

The Critical Viscosity of Xenon (CVX) experiment, which flew on board Space Shuttle flight STS-85 in August 1997, measured the viscosity of xenon near the liquid-vapor critical point. Very close to the critical temperature (Tc = 290 K), the viscosity Η of a pure fluid is expected to diverge as a power law, Η {is proportional to} [(T-Tc)/Tc]-y. Microgravity allowed CVX to make the first direct observation of this divergence. This talk will summarize the scientific results and the unexpected behavior of CVX in orbit.
