Effect of magnetic field on near-wall coherent structures and heat transfer in magnetohydrodynamic turbulent channel flow of low Prandtl number fluids
(2011)A numerical study is carried out of the magnetic field effects on the coherent structures and the associated heat transfer in a turbulent channel flow with constant temperature at the bottom (cold) and top (hot) walls. ... -
Nonlinear resonance in viscous films on inclined wavy planes
(2009)We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ... -
Numerical investigation of momentum exchange between particles and coherent structures in low Re turbulent channel flow
(2011)The interaction between particles and coherent structures is studied by using discrete particle simulation combined with direct numerical simulation of gaseous flow in a vertical channel. A conditional sampling scheme is ... -
Secondary Bjerknes forces between two bubbles and the phenomenon of acoustic streamers
(2004)The translational velocities of two spherical gas bubbles oscillating in water, which is irradiated by a high-intensity acoustic wave field, are calculated. The two bubbles are assumed to be located far enough apart so ... -
Temperature, comfort and pollution levels during heat waves and the role of sea breeze
(2010)During the summer of 2007 several Greek regions suffered periods of extreme heat, with midday temperatures of over 40A degrees C on several consecutive days. High temperatures were also recorded on the east coast of central ... -
Transport and deposition of neutral particles in magnetohydrodynamic turbulent channel flows at low magnetic Reynolds numbers
(2011)The effect of Lorentz force on particle transport and deposition is studied by using direct numerical simulation of turbulent channel flow of electrically conducting fluids combined with discrete particle simulation of the ... -
Vortex buffeting of aircraft tail: Interpretation via proper orthogonal decomposition
(2005)The proper-orthogonal-decomposition method is applied to particle-image-velocimetry (PIV) data to extract the most energetic flow structures of vortex-tail interaction. The reconstructed flowfields, in conjunction with ...
