Abstract

A mathematical model using Fluent 14.0 was implemented in order to describe the flow of Nitrogen and slag under transient and isothermal conditions in the slag splashing process for the improvement of refractory life. The influence of parameters affecting this process and the consequent effects on refractory linings has been investigated applying the model. For a given blow pattern, the influence of parameters such as temperature, density, viscosity and interfacial tension of the fluids involved have been discussed. The results are compared with projection data available in the literature.
