Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed to study the characteristics of the flow in a two-dimensional air ejector in which the center stream entered the mixing chamber at a Mach number of 1.90 while the velocity of the secondary flow was varied from zero to Mach 0.7. Mass flow ratios of the ejector were approximately equal when the pressures of the two streams were equal at the entrance to the mixing chamber. The chamber had a rectangular cross section and converged slightly; its length was equal to 16 times the width. Pressures measured at the walls and the centerline of the flow indicated that a maximum static pressure was reached at 8 widths of the chamber downstream of the nozzle when the flow was completely expanded at the nozzle exit. The maximum static pressure was achieved in less distance for the overexpanded condition and took longer for the underexpanded condition. The flow was always subsonic by the time the maximum pressure position was reached except in the underexpanded case, where the flow remained supersonic throughout the chamber and the maximum pressure was located at the exit to the chamber.

This book was released on 1956 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results indicated increases in auxiliary-inlet pressure recovery with increases in scoop height relative to the boundary-layer thickness. The pressure recovery increased at about the same rate as theoretically predicted for an inlet in a boundary layer having a one-seventh power profile, but was only about 0.68 to 0.75 of the theoretically obtainable values. Under some operating conditions, flow from the primary jet was exhausted through the auxiliary inlet. This phenomenon could be predicted from the ejector pumping characteristics.

This book was released on 1982 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental and theoretical investigation of a planar, two-dimensional constant area ejector with a periodically pulsed or a steady, supersonic driver flow will be presented. The purpose of this investigation was to determine the potential of using unsteady flow techniques to enhance the mixing between high-speed streams interacting within a duct and to improve the overall pressure recovery obtained within an ejector system. This research was motivated by mixing problems which were encountered in high-energy chemical laser systems at the laser fuel-oxidizer nozzle array and within the ejector-diffuser system required to pump the laser effluent for atmospheric discharge.

This book was released on 1964 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow generated by a supersonic jet issuing from the nose of a blunt body upstream in a supersonic flow can fall into two typical classes: (1) a steady flow characterized by a shock layer between two strong shocks, one terminating the jet and the other the free stream, and located at a well determined, relatively short stand-off distance upstream from the nose, and (2) an unsteady flow resembling a jet-spike which penetrates relatively far into the free stream and deflects it through oblique shocks. Shock standoff distances in blunt-interaction flow can be predicted theoretically with considerable accuracy. The limits of existence of this type of interaction can be calculated if empirical evaluations of two parameters appearing in the analytical formulation are supplied. The available experiments yield a first estimate of these parameters but additional data and further refinement of the analysis are needed to obtain a satisfactorily precise correlation.
