摘要:
This is an experimental study on the drag reduction phenomenon in a gas-particle suspension two-phase flow system. The purpose of the research was to examine the effect of static charges carried by the conveyed particles on the drag reduction characteristics of a flowing suspension in horizontal and vertical tubes. A specifically designed experimental loop was used to perform simultaneous pressure drop and particle charge measurements. The charge on the particles flowing in the system was artificially increased using high voltage rod-in-cylinder Corona chargers mounted in the closed loop. The particle charge was measured in a Farraday cage sampling device and the effective current generated by particle impact on a specially designed spherical nickel probe mounted in the two-phase flow was also recorded.
