Abstract
Previous determinations of drag coefficients for both steady and unsteady flow are reviewed for all reported experiments at critical and supercritical Reynolds numbers. The unsolved problems remaining from earlier DRES work were found to be: end effects, dust drag loading, the discrepancies between steady and unsteady flow drag forces, and the need for a further data analysis. A new analysis is also presented for the drag coefficient as a function of flow Mach number and cylinder length-diameter ratio.
