The stability of an inviscid compressible swirling flow between two concentric cylinders is analytically investigated. Two stability criteria are derived for compressible swirling flows under narrow gap approximation by an analytic method analogous to Ludwieg's method. Author: Nan Xia. Jan 01,  · The stability of an axisymmetric flow of viscous gas in a circular pipe, which models the Burgers vortex in the pipe axis neighborhood, is studied within the linear theory framework. Neutral curves for the most unstable disturbances are calculated. The influence of the characteristic Mach number on the flow stability is investigated. It is shown that for a given model velocity distribution the Cited by: 1.

Nov 14,  · The bifurcation and global nonlinear stability of near-critical states of a compressible and axisymmetric swirling flow of a perfect gas in a finite-length straight, circular pipe is studied. This work extends the bifurcation and stability analyses of Wang and Rusak [Phys. Fluids 8, (); Wang and Rusak Phys.

The stability of 20 compressible flows differs from that of incompressible. For unbounded flows, a sufficient condition for stability to supersonic disturbances and an estimate for the growth rate of an unstable supersonic disturbance are given. Academic Press, inc 1.

Viscous and inviscid spatial stability analysis of compressible swirling mixing layers, Physics of Fluids, 20, 11, (). The objective of the course note is to provide a survey of a wide variety of topics in fluid mechanics, including a rigorous derivation of the compressible Navier-Stokes equations, vorticity dynamics, compressible flow, potential flow, and viscous laminar flow. Author(s): Joseph M. Powers. The most teachable book on incompressible flow— now fully revised, updated, and expanded. Incompressible Flow, Fourth Edition is the updated and revised edition of Ronald Panton's classic text. It continues a respected tradition of providing the most comprehensive coverage of the subject in an exceptionally clear, unified, and carefully paced introduction to advanced concepts in fluid mechanics. Compressible flow (or gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is less than (since the density change due to velocity is about 5% in that case).
