Effect of the Reversal of Air Flow Upon the Discharge Coefficient of Durley Orifices (open access)

Effect of the Reversal of Air Flow Upon the Discharge Coefficient of Durley Orifices

Note presenting an experiment to obtain information regarding the relationship between the coefficients for flow in the two directions through an inlet. The results indicate that the ratio of the orifice discharge coefficient from standard orifice to the discharge coefficient from reverse flow is always less than unity, but approaches unity with increasing ratio of box area to orifice area, and that even for a ratio of areas as low as twenty the ratios of the coefficients is not much less than unity.

Apparent Effect of Inlet Temperature on Adiabatic Efficiency of Centrifugal Compressors

From Introduction: "The results of varying only Reynolds number for several equivalent tip speeds are presented and probable reasons for the apparent variation of adiabatic efficiency with inlet temperature are discussed."
