Breakdown of Counterflow Superfluidity in a Disordered Quantum Hall Bilayer by D. K. K. Lee, P. R. Eastham, N. R. Cooper

“…We present a theory for the regime of coherent interlayer tunneling in a disordered quantum Hall bilayer at total filling factor one, allowing for the effect of static vortices. We find that the system consists of domains of polarized superfluid phase. …”

Vortex-Induced Vibration Suppression of a Circular Cylinder with Vortex Generators by Shi-bo Tao, Ai-ping Tang, Da-bo Xin, Ke-tong Liu, Hong-fu Zhang

“…By correlation analysis, it can be concluded that the vortex generators can inhibit the communication between the two shear layers and produce streamwise vortices to generate a disturbance in the spanwise direction.…”

Numerical Simulation of the Static and Dynamic Aerodynamics of a UAV under Wake Flows by Bai-gang Mi, Hao Zhan

“…The results demonstrate that both the steady and unsteady aerodynamics of the fly wing are affected by wake flows: wingtip vortices increase the lift-to-drag ratio and considerably change the dynamic damping; jet flow reduces both the static and dynamic damping; and propeller slipstream leads to slow variations in the dynamic damping and decreases in the lift-to-drag ratio.…”

Analysis of Flow and Pressure Pulsation in Draft Tube of Francis Turbine under Different Guide Vane Opening by REN Haibo, YU Bo, WANG Kui, WANG Luobin

“…In order to explore the influence of the opening of the movable guide vane on the flow and pressure pulsation in the draft tube of the Francis turbine,the steady and unsteady numerical simulations were carried out by establishing a three-dimensional full-flow channel model of a Francis turbine in a power station in southwest China,and the flow characteristics and pressure pulsation of the draft tube of the Francis turbine under different guide vane opening of the rated head were studied.The results show that with the increase in guide vane opening,obvious alternating vortices appear in the straight cone section of the draft tube,which cause low-frequency pressure pulsation in the draft tube.The uniformity of pressure and velocity distribution in the draft tube gradually deteriorates,and the main frequency amplitude of pressure pulsation at the elbow section of the draft tube increases first and then decreases.The vortex zone of the draft tube causes the pressure pulsation of low frequency and high amplitude in the draft tube.…”

Flann O’Brien’s Anti-Manifestos by Julian HANNA

“…One example is the founding editorial of the “anti-magazine” Blather (1934), whose “sardonic laugh” echoes the manifestos – or “anti-manifestos” – of Vorticism and Dada. The manifesto of intertextuality in At Swim-Two-Birds (1939), meanwhile, is more complex: while it appears to be in some ways a sincere statement about the novel as a whole, it is also intensely ironic and self-mocking. …”
