Study of Vortex Breakdown and Pitch up on a Compound Delta Wing [PDF]
INCAS Bulletin, 2019 This paper discusses the calculation of mean pressure on a compound delta wing configuration and its variance to understand vortex breakdown and pitch up on the setup. The configuration of the compound delta wing being used was 50°-60°. The data was used

Shock/Vortex Interaction and Vortex-Breakdown Modes [PDF]
31st Aerospace Sciences Meeting, 1993 Computational simulation and study of shock/vortex interaction and vortex-breakdown modes are considered for bound (internal) and unbound (external) flow domains. The problem is formulated using the unsteady, compressible, full Navier-Stokes (NS) equations which are solved using an implicit, flux-difference splitting, finite-volume scheme.

A coaxial vortex ring model for vortex breakdown [PDF]
Physica D: Nonlinear Phenomena, 2008 A simple - yet plausible - model for B-type vortex breakdown flows is postulated; one that is based on the immersion of a pair of slender coaxial vortex rings in a swirling flow of an ideal fluid rotating around the axis of symmetry of the rings. It is shown that this model exhibits in the advection of passive fluid particles (kinematics) just about ...
