Book Synopsis An Experimental Investigation of the Effect of Adverse Pressure Gradient on Vortex Breakdown by : Gale Edward Treiber
Download or read book An Experimental Investigation of the Effect of Adverse Pressure Gradient on Vortex Breakdown written by Gale Edward Treiber and published by . This book was released on 1973 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of the effect of adverse pressure gradient on the vortex breakdown phenomenon in a diverging tube are presented. Adverse pressure gradient was found to be as significant in determining the breakdown position as were the previously known parameters of Reynolds and circulation numbers. An approximate momentum analysis for predicting the vortex breakdown position was carried out which appears to hold promise as a breakdown predictor. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of the characteristics of stationary and travelling vortex breakdowns in swirling flow in a diverging cylindrical tube are presented and discussed. Basically, three types of vortex breakdown were observed, viz., double helix, spiral, and axisymmetric breakdown. The type and location of the stationary breakdowns were found to be dependent upon the Reynolds and circulation numbers of the flow. The breakdown bubble responded to gradual and abrupt changes in the upstream and downstream flow conditions in a manner analogous to the hydraulic jump in open-channel flow. The observations reported and the evidence presented revealed unmistakably that the vortex breakdown is a finite transition from a uniform state of swirling flow (supercritical) to one (subcritical) featuring a large standing wave, followed by standing wavelets, of finite amplitude.

This book was released on 1998-09-01 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with non-cavitating swirling flows with vortex breakdown in various tubes. Phenomenological and quantitative investigations were carried out at Reynolds numbers as high as 300,000. It was shown that a high Re(D) vortex transitions to its new state (breaks down) via a rapidly spinning spiral form, as demonstrated with 4,000 frame per second video, short exposure time (6 ns) imaging, and Digital Particle Image Velocimetry. Of the known types, the spiral emerges as the fundamental breakdown form and the axisymmetric bubble may now be regarded as a relatively low Re(D) occurrence that is bypassed at sufficiently high Re(D). Some new phenomena were observed at high Re(D): Extremely rapid spiral rotation (over 1,000 revolutions per second), core bifurcation, and changes in the sense of the spiral windings. Familiar features of breakdowns, such as the transition from a jet-like to wake-like axial velocity profile and the rapidly expanding vortex core, were observed in extensive time averaged velocity and turbulence results ascertained with Laser Doppler Velocimetry. However, a mean stagnation point and recirculation were absent in the highest Re(D) flow. The core meandering and stagnation point darting in the turbulent flow field were quantified and discussed in detail.

This book was released on 1968 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of an imposed pressure gradient on the core of a vortex is examined both theoretically and experimentally. The test apparatus consisted of a vortex chamber and a diverging tube. The swirling flow was generated by means of adjustable vanes at the periphery of the vortex chamber and by introducing varying amounts of air. Pressure distributions were obtained along the wall of the tube for various flows and vane settings. In addition, the core of the vortex was photographed by introducing smoke at the axis of the vortex chamber. The theoretical and experimental results show the existence of standing waves arising from the vortex breakdown and the existence of critical conditions, depending on the ratio of the rotational and longitudinal velocity components, beyond which drastic changes of flow structure must occur. The theoretical results were found to be closely related to the observed phenomena. (Author).
