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).

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 2014 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete analysis of the steady flow states of swirling flows in diverging (or converging) pipes was developed. The uniqueness of the steady flow state in a certain swirl range was rigorously proved by using nonlinear functional analysis. The co-existence of multiple steady states of swirling flows in diverging (or converging) pipes for the swirl beyond the uniqueness range were demonstrated numerically. A complete global bifurcation diagram of the flow steady state was also developed by using computational methods. By using the steady flow states obtained by the research described above one may investigate the linear stability of the steady-state flow in various swirl ranges. Due to limited scope of this research, detailed stability analysis will be carried out in future. This research will lead to a deeper understanding of the instability mechanism of the swirling flow in a diverging (or converging) pipe.
