Book Description
This investigation analyzes the operating characteristics of an ejector having a heated primary jet and a constant area mixing section. The effects of several key parameters are determined on the basis of idealized theory. Performance characteristics are described in terms of certain non-dimensional coefficients obtained by a systematic dimensional analysis. In addition, experimental results obtained from a model ejector are presented. These results are in reasonable agreement with the theoretical analysis. Suggestions are made for further improvements both in the theory and in the experimental facility. (Author).

Numerical Analysis of an Axisymmetric Thrust Augmenting Ejector

Pages : 107
Book Description
Use of an ejector is an effective way to increase the thrust produced by a jet. In this thesis project an axisymmetric ejector concept which had been previously explored by experiment was numerically modeled. An existing axisymmetric, internal flow code based on the explicit MacCormack method was modified to incorporate primary nozzle structure and flow injection within the flowfield. Results were compared qualitatively and quantitatively with experimental results to verify the validity of the model. Internal flow structure, difficult to obtain in experiment, is easily examined. This code may be used for parametric analysis of such ejector performance parameters as primary nozzle location, flow injection angle, diffuser area ratio, and inlet geometry to optimize future hardware configurations.

Ejectors for Efficient Refrigeration
Author: Giuseppe Grazzini
Publisher: Springer
ISBN: 3319752448
Category : Technology & Engineering
Languages : en
Pages : 192
Book Description
Encompassing both practical applications and recent research developments, this book takes the reader from fundamental physics, through cutting-edge new designs of ejectors for refrigeration. The authors’ unique vision marries successful design, system optimization, and operation experience with insights on the application of cutting-edge Computational Fluid Dynamics (CFD) models. This robust treatment leads the way forward in developing improved ejector technologies. The book covers ejectors used for heat powered refrigeration and for expansion work recovery in compression refrigerators, with special emphasis on two-phase flows of “natural” fluids within the ejector, i.e. steam and carbon dioxide. It features worked examples, detailed research results, and analysis tools.
