The Batchelor vortex is adopted as the mathematical model of swirling flow. The modes of the Batchelor vortex fall into three broad categories: core modes, algebraic modes and continuous modes. The core modes have been extensively documented but the last two modes have received little attention. The energy growth of those modes are studied by employing

Symposium (International) on Combustion, 1973
Combustion in high-speed swirling flow is an alternate process to the high-intensity, low-weight combustion chamber for gas turbines. The increase in combustion intensity due to the centrifugal force field, the more-rapid dilution, and the greater stability of the cooling film on the outer wall, are the main advantages of this system. Further, the high

Numerical simulation of compulsive swirling flows field on two-phase swirling flows finishing
International Journal of Computer Applications in Technology, 2007Two-phase swirling flows finishing is put forward mainly for hole surface. By theoretical analysis and experimental research, the characteristics of compulsive swirling flows field will directly affect the finishing quality and efficiency. On the basic premise of defining k-e model on swirling flows field, numerical simulation of velocity vector graph,

A liquid in a rigid vessel subjected to external forced excitation becomes unstable under certain conditions due to strong nonlinear effects [1–12]. A variety of modes of liquid surface oscillations occur such as rotary sloshing or swirl. Such oscillations exert significant influence on the safety of cylindrical tanks preserving petroleum, tankers ...

Journal of Physics E: Scientific Instruments, 1987
An experimental investigation of the character and decay of the asymmetrical swirling flow produced by a double right-angle bend in two perpendicular planes has been carried out. Axial velocities have been measured at a total of 36 points on three parallel chords on each of two measurement stations that were 9 diameters and 35 diameters downstream of ...

Journal of Turbomachinery, 1988
The results of extensive laser measurements carried out in the blade passages of a newly designed backswept impeller are presented and discussed. Noticeable distortions of the throughflow patterns and a distinct swirling flow character were found inside the rotor.

Swirled flows and their generalizations
Journal of Applied Mechanics and Technical Physics, 2012New swirled flows (flows in channels, flows around bodies of revolution, and flows with a sink or source on the axis of symmetry) are studied. Group solutions constructed from a supergroup, which are generalizations of conical flows, are considered.

Engineering Computations, 1986
A mathematical model has been developed to study incompressible, isothermal, turbulent, confined, swirling flows. The model solves the conservation equations of mass, momentum, and two additional equations for the turbulent kinetic energy and the rate of dissipation of turbulent kinetic energy. The numerical predictions show a recirculation zone in the

Transonic swirling flow in axisymmetric nozzles
Meccanica, 1976The transonic flow in axisymmetric choked nozzles is computed in the case of a radial distribution of tangential velocity. The flow configuration is obtained by means of a time-dependent technique. The swirling flow is achieved through a particular surface located at the inlet of the nozzle.
