Laminar Free Convection in a Square Enclosure Driven by the Lorentz Force
(2010)A numerical study is presented of laminar free convection flow driven by magnetic forces. An external magnetic field with one spatially varying component is applied to an electrically conducting fluid in a square enclosure. ... -
Magnetic field effect on the cooling of a low-Pr fluid in a vertical cylinder
(2010)Results of direct numerical simulations are presented for the transient and turbulent natural convection cooling of an initially isothermal quiescent liquid metal placed in a vertical cylinder in the presence of a vertical ... -
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 ... -
Performance Analysis of a Laser Ground-Station-to-Satellite Link With Modulated Gamma-Distributed Irradiance Fluctuations
(2010)The performance of a ground-station-to-space laser uplink with a Gaussian-beam wave model subject to turbulence and beam wander effects is the topic of the present study. The modulated gamma distribution is used to describe ... -
Three-dimensional stability of free convection vortices in the presence of a magnetic field
(2012)Three-dimensional (3D) stability of 2D vortical flow of a liquid metal in a cavity of square cross section is examined. Vortices are produced as a result of free convection and internal heating in the cavity in the presence ...
