Analytic models of heterogenous magnetic fields for liquid metal flow simulations
(2009)A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

Direct numerical simulation of turbulent liquid metal flow entering a magnetic field
(2013)This paper presents direct numerical simulations (DNS) of fully developed turbulent liquid-metal flow in a circular duct entering a magnetic field. The case of a magnetohydrodynamic flow leaving a strong magnetic field has ...

Full magnetohydrodynamic solution of liquid-metal flow in an insulating pipe subjected to a strong fringing magnetic field
(2012)This paper addresses liquid-metal flow under a strong, fringing, decreasing magnetic field in an insulating circular pipe by a full resolution of the magnetohydrodynamic (MHD) equations. The aims of the paper are first to ...

MHD flow past a circular cylinder using the immersed boundary method
(2010)The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...

Processing of semi-solid materials using a shear-thickening Bingham fluid model
(Publ by ASME, 1994)Recently the importance of processing metals and metal matrix composites in semi-solid state is growing rapidly. Performing the shape making operations in the semi-solid state provides a better opportunity to control the ...

Thermo-fluid modeling of direct chill casting of metal alloys using an inverse finite element method
(Publ by Computational Mechanics Inc, 1992)Direct chill (DC) casting is used extensively in the production of wrought nonferrous metals and alloys, particularly in the aluminum industry. For alloys, a semi-solid region known as the “mushy zone” and defined by the ...

Thixotropic rheology of semisolid metal suspensions
(2001)Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changes with the processing history due ...

Three-dimensional numerical simulations of magnetohydrodynamic flow around a confined circular cylinder under low, moderate, and strong magnetic fields
(2013)This paper presents three-dimensional direct numerical simulations of liquid metal flow around a circular cylinder placed symmetrically in a rectangular duct, under a wide range of magnetic field intensities. Results are ...
