Coulomb drag between disordered two-dimensional electron gas layers

open access: yes, 1993
We derive and evaluate expressions for the frictional Coulomb drag between disordered two-dimensional electron gas layers. Our derivation is based on the memory-function formalism and the expression for the drag reduces to previously known results in the

Simulation of drag reduced conductors based on a new accurate model using finite element method

open access: yesThe Journal of Engineering, 2019
For improving the reliability of power transmission lines, it is urgent to reduce the horizontal load and wind deviation, while replacing with drag reduced conductors can achieve it without changing the original transmission line path.

Coulomb drag between ballistic quantum wires

open access: yes, 2012
We develop a kinetic equation description of Coulomb drag between ballistic one-dimensional electron systems, which enables us to demonstrate that equilibration processes between right- and left-moving electrons are crucially important for establishing ...

High-Speed Swimsuits and Their Historical Development in Competitive Swimming

open access: yesFrontiers in Psychology, 2019
The goal of this research was to review the experimental studies that have analyzed the influence of “high-speed swimsuits” on sports performance up to the appearance of the model “Jammer” in competitive swimmers. The design was a review following PRISMA

Two-dimensional flows of foam: drag exerted on circular obstacles and dissipation

open access: yes, 2004
A Stokes experiment for foams is proposed. It consists in a two-dimensional flow of a foam, confined between a water subphase and a top plate, around a fixed circular obstacle. We present systematic measurements of the drag exerted by the flowing foam on

Coulomb Drag as a Probe of the Nature of Compressible States in a Magnetic Field

open access: yes, 2003
Magneto-drag reveals the nature of compressible states and the underlying interplay of disorder and interactions. At \nu=3/2 a clear T^{4/3} dependence is observed, which signifies the metallic nature of the N=0 Landau level.

Drag Characteristics and Reduction Test for Hub of Coaxial-rotor Helicopter

open access: yesHangkong gongcheng jinzhan, 2020
The drag of coaxial helicopter hub accounts is more than 50% of the total helicopter's waste drag, so it is necessary to research the drag characteristics and reduction design of the hub. Wind tunnel test is carried out for a coaxial helicopter hub model,
