of the central jet distributor (CJD) burner was defined to express the oxygen supply mode, and the KIVCET process with an MRR ranging from 0.09 to 0.39 was simulated. The results show that there are four..., the chemical reactions associated with the feed are completed with an acceptable dust rate. Key words: KIVCET furnace; central jet distributor (CJD) burner; computational fluid dynamics (CFD); central......

School of Mechanical Engineering, Hunan Institute of Engineering..., Xiangtan 411101, China) Abstract: Simulation model of cobalt crusts crushing process with water jet was established based on SPH method. With simulation research, crushing mechanism of cobalt crusts......
on the turbulence jet model, with respect to Ar-He mixture plasma gas injecting to ambient atmosphere, the temperature filed and velocity field under typical working conditions were investigated... slow. The inner mechanism for such phenomena is due to the complex violent interaction between the high-temperature and high-velocity turbulent plasma jet and the ambient atmosphere. Compared......
