Patterned turbulence and relaminarization in MHD pipe and duct flows
(WILEY‐VCH Verlag, 2014-12)
We present results of a numerical analysis of relaminarization processes in MHD duct and pipe flows. It is motivated by Julius Hartmann's classical experiments on flows of mercury in pipes and ducts under the influence of ...
Transition to Turbulence in the Hartmann Boundary Layer
(WILEY-VCH Verlag, 2007-04)
The Hartmann boundary layer is a paradigm of magnetohydrodynamic (MHD) flows. Hartmann boundary layers develop when a liquid metal flows under the influence of a steady magnetic field. The present paper is an overview of ...
Direct numerical simulation of transition in MHD duct flow
(WILEY‐VCH Verlag, 2011-12)
Transition in the flow of electrically conducting fluid in a square duct with insulating walls is studied by direct numerical simulations. A uniform magnetic field is applied in the transverse direction. Moderate values ...
Subcritical instability of liquid metal channel flow in the presence of a spanwise magnetic field
(WILEY-VCH Verlag, 2007-12)
The linear and nonlinear evolution of perturbations is investigated in a magnetohydrodynamic channel flow with electrically insulating walls. The applied magnetic field is parallel to the walls and orthogonal to the stream. ...
MHD turbulence in a channel with spanwise field
(WILEY-VCH Verlag, 2008-12)
We study turbulent channel flow of an electrically conducting liquid with a homogeneous magnetic field imposed in the spanwise direction. The Lorentz force is modelled using the quasistatic approximation. Direct and ...
Effect of wall conductivity on turbulent channel flow under spanwise magnetic field
(WILEY-VCH Verlag, 2010-12)
The effect of wall conductivity on turbulence in electrically conducting fluid in the presence of a constant magnetic field is considered. A channel flow with a spanwise magnetic field is analyzed using high-resolution ...
