抄録
A compositional separation by thermal diffusion phenomena (Soret effect) in a locally heated rectangular flow channel under 1G and microgravity condition was investigated experimentally and theoretically. Parabolic flight experiments on thermal diffusion were conducted using binary gas mixture systems of He-SF_6 and Ne-SF_6. Under the conditions of various G-levels, the local gas mixture was sampled through a fused quartz tube (75・m I.D. and 90cm in length) inserted into the flow channel, and analyzed by means of a quadrupole mass spectrometer evacuated by a turbo molecular pump and diaphragm type dry vacuum pump. Gas flow, heat and mass transfer in a rectangular flow channel under 1G and ・G were also predicted numerically using a steady state three-dimensional simulation code. The calculated results of the concentration distribution in the channel agreed well with the experimental ones under almost all conditions except for the microgravity Ne-SF_6 system.
