The attraction of the confined swirling flow generated inside an enclosed cylinder by the constant rotation of one of its endwalls to a study of vortex breakdown is that the flow is defined by only four variables, these being the height H and radius R of the cylinder, the constant angular speed of rotation of the endwall f~ and the kinematic viscosity t~. These four variables are used to define...

This study examines the flow field dynamics of bluff-body stabilized swirling and non-swirling flames produced from Cambridge/Sandia Stratified Swirl Burner. burner has been used in previous studies as a benchmark for high-resolution scalar velocity measurements validating numerical models. The was designed to create reacting conditions that are representative turbulent flows modern combustion ...

Stability problem of an axisymmetric swirling flow a viscous incompressible fluid with respect to nonaxisymmetric perturbations is considered. The system ordinary differential equations for the amplitude functions solved numerically by Runge-Kutta method and orthogonalization procedure. Solutions at neighborhood singular points are obtained Frobenius method. maximum amplification coefficients p...

The shear swirling flow vibration cementing (SSFVC) technique rotates the downhole eccentric cascade by circulating cementing fluid. It makes the casing eccentrically revolve at high speed around the borehole axis. It produces strong agitation action to the annulus fluid, makes it in the state of shear turbulent flow, and results in the formation of pulse pressure which affects the surrounding ...

ABSTRACT Local measurements and 3-D CFD simulations in GasLiquid cylindrical Cyclone (GLCC) separators are scarce. The main objective of this study is to conduct local measurements and 3-D CFD simulations to understand the swirling flow behavior in a cylindrical cyclone with one inclined tangential inlet. Axial and tangential velocities and turbulent intensities across the GLCC diameter (ID=3.5...
