Equilibration and other dynamic properties of fluids near the liquid-vapor critical point

Professor Horst Meyer is interested in the properties of fluids near their liquid-vapor critical point. These show a singular behavior as the critical point is approached. For instance the compressibility and the specific heat diverge, and so does the thermal conductivity. The thermal diffusivity, however, tends to zero, and the equilibration times become very long. The program at Duke, supported by a NASA grant, has focussed on a comprehensive study of these properties in 3He and in 3He-4He mixtures. Recently the equilibration mechanism of 3He near the critical point was investigated. The most recent studies deal with heat transfer in 3He, where the transition from conduction to convection and to early turbulence are investigated and compared with predictions and numerical simulations by several groups in Japan and in France. These studies are relevant to the NASA microgravity program.

Earlier research dealt with heat transfer in liquid 4He and 3He-4He mixtures near the superfluid transition, and with the investigation of the orientational ordering in solid hydrogen and deuterium by various methods (NMR, heat transport, acoustics).
