Considerations on Steady- and Nonsteady-Flow Ejectors,
Abstract
A broad examination is made of the flow induction spectrum, from the steady-flow to the pulsating-flow ejector, with special attention to the relationships of dissipation and performance to nonsteadiness, size of migrating eddies, and diffusion. A boundary-value approach is recommended for the comparative evaluation of induction modes. The limits of attainable thrust or lift augmentation are shown to be in some cases a good deal higher than those predicted by initial-value analyses.
