Effect of phonon-boundary scattering on phonon-drag factor in Seebeck coefficient of Si wire

AIP Advances, 2020
For highly efficient thermoelectric devices with Si nanostructures, we have fabricated and characterized micro/nanometer-scaled Si wires preserving the phonon-drag effect in order to observe the impact of phonon-boundary scattering on the phonon-drag ...

Motion characteristics and drag coefficient of bubbles in liquid lead-bismuth eutectic

He jishu
BackgroundSteam generator tube rupture (SGTR) accidents in lead-bismuth cooled fast reactors result in the generation of numerous steam bubbles owing to the interaction of the high-temperature liquid lead-bismuth eutectic (LBE) from the primary circuit ...

A General Circulation Model for Gaseous Exoplanets with Double-Gray Radiative Transfer

, 2011
We present a new version of our code for modeling the atmospheric circulation on gaseous exoplanets, now employing a "double-gray" radiative transfer scheme, which self-consistently solves for fluxes and heating throughout the atmosphere, including the ...

Using wind setdown and storm surge on Lake Erie to calibrate the air-sea drag coefficient.

PLoS ONE, 2013
The air-sea drag coefficient controls the transfer of momentum from wind to water. In modeling storm surge, this coefficient is a crucial parameter for estimating the surge height. This study uses two strong wind events on Lake Erie to calibrate the drag

Wind tunnel tests on airfoil boundary control using a backward opening slot [PDF]

This report presents the results of an investigation to determine the effect of boundary layer control on the lift and drag of an airfoil equipped with a backward opening slot. Various slot locations, widths of opening, and pressures, were used.

Coulomb drag in graphene: perturbation theory

, 2012
We study the effect of Coulomb drag between two closely positioned graphene monolayers. In the limit of weak electron-electron interaction and small inter-layer spacing ($\mu_{1(2)}, T\ll v/d$) the drag is described by a universal function of the ...
