抄録

Gas flow and heat transfer in a horizontal flow channel partially heated from below under 1G and reduced gravity have been studied experimentally and theoretically. Flow visualization and temperature measurements were conducted using short term microgravity facilities, i. e. a drop shaft and parabolic flights. Transient behavior of the gas flow patterns in accordance to the time dependent gravity changes were visualized by means of the suspended TiO₂ particles, illuminated by a laser sheet. Observed flow patterns showed fairly good agreement with the results of three dimensional unsteady numerical simulations. The criteria for the onset of transverse and longitudinal roll cells were mapped on Grashof number (Gr) vs. Reynolds number (Re) plane and well explained by the correlation lines previously reported by the authors based on steady two dimensional numerical simulations.
