An Experimental Investigation of Two-Phase, Two-Component Flow in a Horizontal, Converging-Diverging Nozzle

Description: A discussion is presented of an investigation of the flow characteristics in a horizontal, converging-diverging nozzle for a two-phase, air- water system. The primary consideration, to determine the effects of accelerating the liquid phase by the gaseous phase, was measured in terms of nozzle exit water velocity, exit slip ratio, and exit acceleration factor. A gamma-ray-attenuation technique was used to determine these values by determining the average cross-sectional void fraction, the ratio … more

Mutual Charge Neutralization of Gaseous Ions

Description: The problem of the bimolecular rate constant, alpha , for the mutual charge neutralization reaction (ion-ion recombination) for ions formed by the vacuum ultraviolet photolysis of nitric oxide is considered. The pressure dependence of alpha over a pressure range of 10 to 600 torr for mixtures of a few hundred microns of NO with He, Ar, Kr, Xe, H/sub 2/, D/sub 2/, and N/sub 2/ was measured. From the low-pressure limit of alpha , the rate constant for charge neutralization in the absence of a thi… more
