Viscous Effects on the Instability of an Axisymmetric Jet
Author: National Aeronautics and Space Adm Nasa
Publisher: Independently Published
ISBN: 9781728916224
Category : Science
Languages : en
Pages : 30
Book Description
The stability characteristics of a laminar, axisymmetric jet, issuing from fully developed Poiseuille flow, are investigated. The jet preferred frequency, as inferred from surveys of u'-spectra, is found to yield a Strouhal number (St) that depends on the Reynolds number (R); St and R are based on the jet diameter (D) and the average velocity (U sub av) at the jet origin. The value of St increases with increasing R in the range 400 less than approximately R less than approximately 4000, attaining an asymptotic value of about 0.45. Flow visualization confirms that the instability is primarily in a helical mode, as predicted by stability analyses. Analyses do predict a similar St versus R variation in approximately the correct St-range. However, the R-range where this is predicted is lower than that found experimentally. Zaman, K. B. M. Q. and Seiner, J. M. Glenn Research Center; Langley Research Center RTOP 505-62-21

Modeling Axisymmetric Flows
Author: Stanley Middleman
Publisher: Academic Press
ISBN: 0080536638
Category : Technology & Engineering
Languages : en
Pages : 319
Book Description
This concise book is intended to fulfill two purposes: to provide an important supplement to classic texts by carrying fluid dynamics students on into the realm of free boundary flows; and to demonstrate the art of mathematical modeling based on knowledge, intuition, and observation. In the authors words, the overall goal is make the complex simple, without losing the essence--the virtue--of the complexity. Modeling Axisymmetric Flows: Dynamics of Films, Jets, and Drops is the first book to cover the topics of axisymmetric laminar flows; free-boundary flows; and dynamics of drops, jets, and films. The text also features comparisons of models to experiments, and it includes a large selection of problems at the end of each chapter. Contains problems at the end of each chapter Compares real-world experimental data to theory Provides one of the first comprehensive examinations of axisymmetric laminar flows, free-boundary flows, and dynamics of drops, jets, and films Includes development of basic equations Written in a style suitable for use as a textbook
