The Okubo-Weiss Criteria in Two-Dimensional Hydrodynamic and Magnetohydrodynamic Flows
B. K. Shivamoggi, G. J. F. van Heijst, L. P. J. Kamp
The Okubo [2]-Weiss [3] criterion is recast by using the 2D hydrodynamic Beltrami condition (Shivamoggi et al.[13]) that approximates the slow flow-variation ansatz imposed in its…

Divorticity and Dihelicity In Two-Dimensional Hydrodynamics
B. K. Shivamoggi, G. J. F. van Heijst, J. Juul Rasmussen
A framework is developed based on the concepts of {\it divorticity} ($\equiv\nabla\times\bfo$, $\bfo$ being the vorticity) and $\textit{dihelicity} g \lp \equiv\bfv\cd…

Vortex Stretching and Reconnection in a Compressible Fluid
Bhimsen K. Shivamoggi
Vortex stretching in a compressible fluid is considered. Two-dimensional and axisymmetric cases are considered separately. The flows associated with the vortices are perpendicular…
