The fi gure shows the contour plot of the time averaged velocity fi eld in the mini-LIMMCAST mold model. Results are calculated by unsteady RANS simulations. Despite the symmetrical pattern shown in this fi gure, the study reveals that strong deviations can occur due to choice of the turbulence model and order of discretization in such kind of fl ows.

Using a Mathematical Model of Counter-Current Flow in a Blast Furnace to Evaluate Reducibility of Iron-Ore-Bearing Raw Materials
320The paper deals with a mathematical model of counter-current fl ow in a blast furnace for a complex evaluation of iron-ore bearing raw materials reducibility. It is based on laboratory tests results and model calculation to predict the parameters of the reduction process and specifi c consumption of carbon in the blast furnace by Rist.
