CFD simulation of multiphase melt flows in steelmaking converters

The three-dimensional, transient, non-isothermal flow of melt, slag and oxygen/argon is simulated for a 335 t combined blowing converter with six-hole top lance and 14 bottom tuyeres. The calculation is based on the Reynolds averaged Navier-Stokes (RANS) equations and the Standard k-epsilon model. The time-dependent formation of the melt...

Mixing enhancement by shock impingement in a generic scramjet combustion chamber

The present paper focuses on the mixing improvement in a generic supersonic combustion chamber for a fixed combustion chamber height with wall injection. On the one hand, internal shocks are employed to increase mixing and penetration, on the other hand injector design and spacing are investigated to achieve good penetration and mixing. With...
