This research study indicates that the classical Reynolds number dependency of the coefficient of drag for gases forced into packed beds is not correct at high Reynolds numbers. Care must also be taken to account for boundary layer wall effects that occur when the ratio of test chamber diameter to bead particle diameter is too small. Included is a review of the literature pertaining to gaseous flow resistance in packed beds. An existing test facility used in a previous study was found unsatisfactory, and necessary corrections were made to obtain normalized pressure gradient measurements at increasingly high Reynolds numbers. The resultant data was organized into a new correlation for the coefficient of drag, that is Fv=150+3.89Re1−φ0.87 This formula was developed for air flowing over spherical particles at Reynolds numbers ranging from 103–105.

This paper presents the results of an experimental investigation on the discharge coefficient of a quadrant-edge orifice meter at high Reynolds numbers (in the range of 20,000 to 600,000). Results show that the coefficient of discharge can be related qualitatively with the drag of a cylinder in an infinite fluid medium. Results regarding upper constancy limit and reproducibility are also furnished.
