An Analysis of the Incompressible Two-Dimensional Jet Ejector


Rose, James Robert (1969) An Analysis of the Incompressible Two-Dimensional Jet Ejector. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/Q1EZ-AW49.


A general method for calculating the performance of two-dimensional jet ejector systems is presented, with special emphasis on those qualities desired in thrust augmenter devices. The nature of the viscous-inviscid interaction problem is examined and a "frictionless" model is defined. The equations are solved for the particular parametric problem of a single jet in a finite length shroud of uniform height. The flow in the "recovery" or confined-mixing region is discussed for this model and techniques are developed which may be applied to devices with diffusing systems. The solutions presented for the free-mixing or interaction region are shown to agree with the simple channel flow studied analytically and experimentally by Curtet.
