Axisymmetric Vortex Breakdown in a PipeS
نویسنده
چکیده
A recent theory of the nearly axisymmetric vortex breakdown in a pipe is presented. We study the motion of an axisymmetric and inviscid swirling ow in a pipe with certain boundary conditions that may reeect the physical situation. The theory is built of global analysis of solutions of the Squire-Long equation and linear stability analysis of these solutions. The theory uniies the major previous theoretical approaches and provides for the rst time a consistent explanation of the physical mechanism leading to the vortex breakdown phenomenon as well as the conditions for its occurrence.

Comparisons of Experimental and Numerical Results for Axisymmetric Vortex Breakdown in Pipes
Experimental data for the bubble mode of breakdown in pipe ows is compared with calculations of the axisymmetric form of the Navier-Stokes equations. The location of breakdown in the calculations is found to be extremely sensitive to the inlet conditions; however, generally good agreement between the experimental and numerical breakdown locations is obtained. Detailed comparisons of the velocit...
متن کاملThe Role of Vorticity Dynamics in Vortex Breakdown
1 Abstract The role of vorticity dynamics in vortex breakdown is examined in a theoretical and computational study. Under the assumptions of steady, incompressible, axisymmetric, invis-cid ow, a theory is developed concerning the interaction of vortex tilting and stretching in the breakdown process. This analytic theory is then connrmed using an unsteady, incompressible, axisymmetric viscous ow...
متن کاملAxisymmetric vortex breakdown Part 2. Physical mechanisms
The physical mechanisms for vortex breakdown which, it is proposed here, rely on the production of a negative azimuthal component of vorticity, are elucidated with the aid of a simple, steady, inviscid, axisymmetric equation of motion. Most studies of vortex breakdown use as a starting point an equation for the azimuthal vorticity (Squire 1960), but a departure in the present study is that it i...
متن کاملA model for the onset of breakdown in an axisymmetric compressible vortex
A simple inviscid model to predict the onset of breakdown in an axisymmetric vortex is proposed. Three problems are considered: the shock-induced breakdown of a compressible vortex, the breakdown of a free compressible vortex, and the breakdown of a free incompressible vortex. The same physical reasoning is used in all three problems to predict the onset of breakdown. It is hypothesized that br...
متن کاملThe sensitivity of steady vortex breakdown bubbles in confined cylinder flows to rotating lid misalignment
Recent experimental observations using tracer visualization techniques have suggested that even for low Reynolds number flows, the steady vortex breakdown bubble in a torsionally driven cylinder is not axisymmetric and has an inflow/outflow asymmetry at its tail. These results seem to suggest that this type of vortex breakdown is closer in structure to that observed in the open vortex tube than...
