Multi-fluid Mathematical Model for Blast Furnace and Its Solution

To understand,control and improve the blast furnace process,more efforts are made to develop mathematical models relevant to it,and the multi-fluid blast furnace model is the latest reaction-kinetic one for the whole blast furnace.It was based on the multi-fluid theory,kinetics,transport phenomena theory and computational fluid dynamics,with the mutual interphase interactions fully taken into account.The application results revealed that the multi-fluid model is a complicated,comprehensive and effective tool for blast furnace process simulation available to both 2-D and 3-D in-furnace phenomena and accurate prediction of the operational parameters under given conditions.
