Buoyancyassisted mixed convection in a vertical channel with spatially periodic wall temperature
(2013)The influence of a spatially periodic temperature boundary condition on the laminar mixed convection in an upward flow between two vertical parallel plates is numerically studied. A detailed assessment is presented of the ... 
Large eddy simulation of gasparticle turbulent channel flow with momentum exchange between the phases
(2011)This paper presents results of a large eddy simulation (LES) combined with Lagrangian particle tracking and a pointforce approximation for the feedback effect of particles on the downward turbulent gaseous flow in a ... 
Linear and nonlinear stability of hydrothermal waves in planar liquid layers driven by thermocapillarity
(2013)A shallow planar layer of liquid bounded from above by gas is set into motion via the thermocapillary effect resulting from a thermal gradient applied along its interface. Depending on the physical properties of the liquid ... 
Magnetic field effect on the cooling of a lowPr 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 ... 
Magnetohydrodynamic natural convection in a vertical cylindrical cavity with sinusoidal upper wall temperature
(2009)A series of numerical simulations were performed in order to study liquid metal MHD natural convection in a vertical cylindrical container with a sinusoidal temperature distribution at the upper wall and the other surfaces ... 
MAGNETOHYDRODYNAMIC NATURAL CONVECTION OF LIQUID METAL BETWEEN COAXIAL ISOTHERMAL CYLINDERS DUE TO INTERNAL HEATING
(2014)Direct numerical simulation results are presented of magnetohydrodynamic liquid metal flow between two vertical coaxial cylinders under the effect of internal heating and a horizontal magnetic field. The end walls are ... 
Natural convection of liquid metal in a vertical annulus with lateral and volumetric heating in the presence of a horizontal magnetic field
(2011)MHD free convection of a liquid metal is studied in a closed vertical annulus in which the upper and bottom walls are adiabatic while the cylindrical walls are kept at different temperatures. The flow is driven by two ... 
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 ...
