ResumoUm modelo matemático tridimensional, via software Fluent 14.0, de modo a descrever o fluxo, em regime transiente e isotérmico dos fluidos escória e nitrogênio, foi utilizado para avaliar o comportamento de slag splashing em um convertedor a oxigênio com o propósito de reparar as regiões desgastadas do revestimento de trabalho deste reator. Para um dado padrão de sopro foi investigou-se o efeito de parâmetros tais como temperatura, densidade, viscosidade e tensão interfacial. Os resultados são comparados com dados de projeção disponíveis na literatura. Palavras-chave: Convertedor a oxigênio; Slag splashing; Modelagem matemática.
A STUDY ON THE INFLUENCE OF PHYSICAL PROPERTIES OF SLAG AND OF OPERATIONAL PARAMETERS ON THE SPLASHING SLAG PROCESS AbstractA mathematical model using Fluent 14.0 was implemented in order to describe the flow of Nitrogen and slag under transient and isothermal conditions related to slag splashing. The purpose was to study the influence of parameters affecting the repair of the working refractory lining. For a given blow pattern the influence of parameters such as temperature, density, viscosity and interfacial tension was assessed. The results are compared with projection data available in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
