Abstract

Injection of gas-carried powders by an immersed lance is among the most popular desulphurization methods in many metallurgical processes. This paper proposes a CFD algorithm to simulate the transient multiphase flow in the powder injection process, using the volume of fluid (VOF) method to calculate the gas-liquid flow and discrete phase model (DPM) to capture particles motions. The k- model is also adopted to solve the turbulent flow field. Experimental results on a water model are compared with CFD simulation results and qualitative agreement is found. Then, the CFD algorithm is used to numerically study the multiphase flow in the powder injection process, with an emphasis on the particles distribution. Influences on powders distribution of lance entering length and injection speed are also investigated.
