Experimental and computational study on fluid flow-solid particles interaction associated with entrainment behavior of the particles in the industrial furnaces

산업용 로 내 고체 미립자의 거동 예측을 위한 유동-고체입자 간 비산에 관한 실험과 해석

In the industrial furnaces or reactors, entrainment of the material particles is one of the important issues from the point of view of efficient material-use. The particles of solid phase which has submicron unit are easily entrained with gas phase as a reacting agent or product, and it causes a loss of the material. In this study, wind-tunnel experiment is carried out to interpret the distribution of the particles entrained along the tunnel length. Through CFD-based computational analysis of the experiment, availability of result from the CFD analysis associated with particle size distribution and gaseous velocity to practical system is evaluated.
