Continuous casting is a process whereby molten metal is solidified into a semi-finished billet, bloom, or slab for subsequent rolling in finishing mills; it is the most frequently used process to cast not only steel, but ...

Polymer electrolyte fuel cells (PEFCs) are versatile electrochemical devices that convert the chemical energy of a fuel, such as hydrogen, and an oxidant, such as air-derived oxygen, directly into electricity, both cleanly ...

Asymptotic methods are employed to revisit an earlier model for oscillation-mark formation in the continuous casting of steel. A systematic non-dimensionalization of the governing equations, which was not carried out ...

The problem of fast viscous steady Rayleigh-Bénard convection in a rectangular enclosure is revisited using asymptotic and numerical methods. There are two generic cases: in the first, there is zero shear stress at all ...
