Classical and quantum regimes of two-dimensional turbulence in trapped Bose-Einstein condensates

, 2012
We investigate two-dimensional turbulence in finite-temperature trapped Bose-Einstein condensates within damped Gross-Pitaevskii theory. Turbulence is produced via circular motion of a Gaussian potential barrier stirring the condensate. We systematically

Spectral kinetic energy transfer in turbulent premixed reacting flows

Physical Review E, 2016
Spectral kinetic energy transfer by advective processes in turbulent premixed reacting flows is examined using data from a direct numerical simulation of a statistically planar turbulent premixed flame. Two-dimensional turbulence kinetic-energy spectra conditioned on the planar-averaged reactant mass fraction are computed through the flame brush and ...

Parametric Optimization of PEDOT:PSS Aerosol Jet Printing for Enhanced Line Morphology in Flexible Electronics

Advanced Electronic Materials, EarlyView.
This work maps and optimizes aerosol‐jet printing of PEDOT:PSS on flexible polyimide. By co‐tuning carrier and sheath gas flows, print speed, and solvent composition with surface activation, continuous, uniform microlines with sharp edges and minimal overspray are achieved.

Examining OpenFOAM-based LES analysis in terms of inviscid energy conservation and viscous turbulence decay

Mechanical Engineering Journal
The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical ...

Stellar wind bubbles around WR and [WR] stars [PDF]

, 2002
We study the dynamics of stellar wind bubbles around hydrogen-deficient stars using numerical simulations with time- and ion dependent cooling. We consider two types of hydrogen-deficient stars, massive WR stars, producing Ring Nebulae, and low mass [WR]

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...
