N2 - Liquid droplets entrained in concurrent gas flows were investigated under reduced gravity condition produced by parabolic flight paths onboard a NASA C-9 research aircrafts. Reduced gravity results were compared with terrestrial ones. Microgravity tests were performed at two water flow rates,. The results shows that pressure drop in the test section is higher under reduced gravity as compared to normal gravity. Preliminary results indicate that for horizontal or slightly inclined channels in normal gravity, gravity plays a stabilizing role. It is shown that critical gas velocities characterizing the entrainment onset for reduced gravity tests are lower than the corresponding normal gravity results at the same water flow rate.
