BPS Vortices in Non-relativistic M2-brane Chern-Simons-matter Theory

We study BPS vortices in the mass-deformed non-relativistic N = 6 U(N)k × U(N)−k Chern-Simons-matter theory. We focus on the massive deformation that preserves the maximal N = 6 supersymmetry, and consider a non-relativistic limit that carry 14 supercharges. In this non-relativistic field theory we find Jackiw-Pi type exact vortex solutions combined with S3 fuzzy sphere geometry. We analyse the...

Discharge Coefficient in Vertical Intakes with Additional Plates

One of the causes of perturbation at vertical intakes is the happening of vortices with an air core. The vortices with an air core occur whenever the submergence of the intake is less than a critical value. Anti-vortex devices and specially plates are used to avoid the negative effects of the air-core vortices. If plates are used, then the geometry of them should be studied experimentally. Acco...

Design and Implementation of Fuzzy Logic Controller for Wing Rock

The wing rock phenomenon is a high angle of attack aerodynamic motion manifested by limit cycle roll oscillations. Experimental studies reveal that direct control and manipulation of leading edge vortices, through the use of ‘blowing’ techniques is effective in the suppression of wing rock. This paper presents the design of a robust controller for the experimental implementation of one such ‘bl...

Stall Vortex Shedding over a Compressor Cascade (RESEARCH NOTE)

The unstable flow with rotating-stall-like (RS) effects in a rotor-cascade of an axial compressor was numerically investigated. The RS was captured with the reduction in mass flow rate and increasing of exit static pressure with respect to design operating condition of the single rotor. The oscillatory velocity traces during the stall propagation showed that the RS vortices repeat periodically,...
