Measurement of thermophoretic parameters for binary gas mixtures
The thermophoretic velocity of a particle in a gas mixture is measured by means of a microgravity experiment. Adopted particles are PMMA spheres of 2.91 mm in mean diameter, and gas mixtures chosen are argon–nitrogen, argon–carbon dioxide, and nitrogen–carbon dioxide. The temperature gradient and...

| description | The thermophoretic velocity of a particle in a gas mixture is measured by means of a
microgravity experiment. Adopted particles are PMMA spheres of 2.91 mm in mean
diameter, and gas mixtures chosen are argon–nitrogen, argon–carbon dioxide, and
nitrogen–carbon dioxide. The temperature gradient and the pressure are 60 K/mm and
70 kPa, respectively. Terminal velocities of particles suspended in a gas are individually
measured. The tangential momentum accommodation coefficient is estimated from
experimental result by assuming the thermal accommodation coefficient at unity, and it
is compared with predictions calculated from values of composing pure gases by means of
some methods given in references; among those methods, the intermolecular-interaction�based method is found to be the best for all mixture conditions. |
