FIG. 1.

Variation of tangential momentum accommodation coefficient with Knudsen number, as reported by different researchers.

FIG. 2.

Variation of tangential momentum accommodation coefficient with Knudsen number for monatomic gases, as reported by different researchers. For a given gas (example helium), TMAC varies from as much as 0.87–0.94. The relatively large variation may be attributed to the different techniques employed and their associated uncertainties.

FIG. 3.

Variation of tangential momentum accommodation coefficient with Knudsen number for diatomic gases, as reported by different researchers. The reason for the large scatter between is discussed in the text.

FIG. 4.

Variation of second slip coefficient with Knudsen number, as reported by different researchers. The curves with both lines and symbols are experimentally determined, while the remaining (just lines) are from theoretical predictions.

Tables

Generic image for table
TABLE I.

TAMC values as reported by Millikan (Ref. 15).

Generic image for table
TABLE II.

Recalculation of TMAC values by Buckley and Loyalka (Ref. 16), using the data of Millikan (Ref. 15).

Generic image for table
TABLE III.

Value of TMAC based on the data of Kuhlthau (Ref. 20), as deduced by Agrawal and Prabhu (Ref. 21).

Generic image for table
TABLE IV.

TMAC from the spinning rotor gauge as calculated from data tabulated in the paper of Comsa et al. (Ref. 24). The material of rotor is steel. The uncertainty quoted is for helium and for xenon at lowest pressure for which the measurements were made. The Knudsen number is greater than unity for these measurements.

Generic image for table
TABLE V.

TMAC from the spinning rotor gauge of Tekasakul et al. (Ref. 26) and Bentz et al. (Ref. 27). The material of rotor is steel. The mean, standard deviation, and Knudsen number values are calculated from data tabulated in these articles.

Generic image for table
TABLE VI.

TMAC as determined from the plots in Colin et al. (Ref. 43).

Generic image for table
TABLE VII.

TMAC as reported by Suetin et al. (Ref. 47).

Generic image for table
TABLE VIII.

TMAC as reported by Porodnov et al. (Ref. 48). Note that the values for helium, neon, and argon are identical to that in Table VII and are therefore not included here.

Generic image for table
TABLE IX.

TMAC as reported by Shields (Refs. 49 and 50).

Generic image for table
TABLE X.

TMAC as reported by Blanchard and Ligrani (Ref. 51). The Knudsen number range for their experiments is 0.0025–0.031. The value reported is the mean of three channels with heights ranging between 6.85 and .

Generic image for table
TABLE XI.

Values of slip coefficients proposed in the literature through theoretical considerations [adapted from Dongari et al. (Ref. 54)].

Generic image for table
TABLE XII.

Values of slip coefficients and TMAC as reported by Sreekanth (Ref. 30), Ewart et al. (Refs. 41 and 56) and Maurer et al. (Ref. 55).

Generic image for table
TABLE XIII.

TMAC as reported by Sazhin et al. (Ref. 61). The Knudsen number for their experiments is greater than 100.

Generic image for table
TABLE XIV.

TMAC as reported by various researchers. Note that data from both experimental and numerical methods are included in the table. The data have been separated out for monatomic and nonmonatomic gases.

Generic image for table
TABLE XV.

Mean TMAC from all reported values for rare gases. These value appear valid for commonly employed surface materials and the entire range of Knudsen number.
