“…I t is clear th at the theory cannot explain the experimental results for HD. This is not very surprising, since this theory has failed in the case of HD also for other low pressure effects, such as the thermomagnetic pressure difference [12] and the Knudsen effects on the flow birefringence [13,14], In summary, one remarks th a t the present experiments in combination with Vestner's theory permit the boundary layer contribution to be separated experimentally from the pure bulk term (5. For this bulk term, very good agreement between experiment and theory is found for the gases CO, N 2 and CH4.…”

In a rarefied polyatom ic gas stream ing through a rectangular channel, an external m agnetic field produces a heat flux perpendicular to the flow direction. Experim ents on this "viscom agnetic heat flux" have been performed for CO, N 2 , CH4 and H D at room temperature, w ith different orientations o f the magnetic field. Such m easurem ents enable one to separate the boundary layer contribution from the purely bulk contribution by means o f the theory recently developed by Vestner. Very good agreem ent is found between the experim entally determined bulk contribution and the theoretical Burnett value for CO, N 2 and CH4 , y e t the behavior o f H D is found to be anomalous.

“…Flow birefringence. Flow birefringence measurements have been carried out for HD-He binary mixtures by Baas et al [33]. They report Á=ðÁÞ HD , in which ÁðX HD Þ and ðÁÞ HD are the frequency shifts due to flow birefringence in a HD-He mixture with mole fraction X HD of HD and in pure HD, respectively.…”

“…Relaxation phenomena that have been experimentally determined for HD-He mixtures include (i) rotational relaxation [28], (ii) viscomagnetic effect measurements [34], thermomagnetic effects [36], thermal diffusion field-effects [37] and (iii) flow birefringence [33].…”

“…In addition, none of the usual transport-relaxation phenomena have been examined for the D 2 -He interaction or for 3 He-hydrogen interactions. Transport and/ or relaxation data available for HD and D 2 -helium binary mixtures include, specifically: diffusion [18][19][20][21][22][23], thermal conductivity [24][25][26], rotational relaxation [27,28], thermal diffusion [29][30][31][32], flow birefringence [33], viscomagnetic [34] and thermomagnetic [35,36] effects and thermal diffusion field effects [37]. In addition, existing related interaction second virial coefficient data available from second virial coefficient measurements in isotopomeric hydrogen-helium mixtures [38,39] have been compiled by Dymond and Smith [40].…”

The comprehensive comparison between calculated bulk non-equilibrium properties of hydrogen-helium isotopomeric mixtures and experiment that has previously been carried out for H 2 -helium mixtures [2004, Molec. Phys., submitted] has been extended to mixtures of HD, D 2 and T 2 with 3 He and 4 He. For HD-4 He mixtures, comparison is also made, where possible, with previous calculations of Ko¨hler and Schaefer [1983, Physica A, 120, 185]. The phenomena examined herein include low temperature interaction second virial coefficients, binary diffusion and thermal conductivity coefficients, rotational relaxation, transport property field effects and flow birefringence. Scattering calculations have been carried out for the HD-He PES of Schaefer and Ko¨hler [1985, Physica A, 129, 469], and for both the Ko¨hler-Schaefer and Tao [1994, J. chem. Phys., 100, 4947] potential surfaces for the D 2 -He and T 2 -He interactions. Comparisons between calculated and experimental results for HD, D 2 , T 2 -He mixtures confirm the conclusion, reached earlier from the H 2 -He comparisons, that these potential surfaces are very close to the correct one for the hydrogen-helium interaction, and that the small differences between them cannot be distinguished readily by measurements of bulk gas phenomena unless the attendant experimental uncertainties are better than AE0:3%.
