Numerical and theoretical study on ‘vortex breakdown’

International Journal of Computer Mathematics, 2011
Through our extensive theoretical and numerical study, we present two theorems on vortex tubes and one corollary on ‘vortex breakdown’. First, we addressed that vortex cannot have ends inside the flow field and the only vortex tube that exists inside the flow field is the ring-like vortex with or without legs on the wall. In addition, we found that the

The Nonlinear Stability of Vortex Flows and Vortex Breakdown

1994
On the condition of zero gradient in z direction\((\partial \,/\,\partial \,z = 0)\), a new model is proposed for the study on the stability of vortex motion. One beneficial character of the model is that two of the three vorticity transport equations, in fact, become linear, but the stretching of vorticity is still an essential mechanism.

Vortex Breakdown in Swirling Conical Flows

AIAA Journal, 1971
This paper describes some experiments in swirling flows in a mildly diverging cylindrical tube in which three types of vortex breakdown were observed: double-helix and spiral forms (followed by turbulent mixing), and axisymmetric form (often followed by a spiral breakdown, then by turbulent mixing). The type and location of the breakdowns were found to

Criterion for vortex breakdown on shock wave and streamwise vortex interactions

Physical Review E, 2014
The interactions between supersonic streamwise vortices and oblique shock waves are theoretically and numerically investigated by three-dimensional (3D) Navier-Stokes equations. Based on the two inequalities, a criterion for shock-induced breakdown of the streamwise vortex is proposed.
