【Abstract】 Anode baking furnace was studied and simplified for modeling request to explore the problem of anode baking furnace on anode baking quality. Physical model of anode baking furnace was established with the boundary conditions and the modeling assumptions by the commercial software Fluent. Based on PDF combustion model, anode baking furnace was studied numerically by the combination of computational heat transfer and computational fluid dynamics. The relationship among fluid field, temperature field and concentration field, as well as their impacts on anode baking quality, was analyzed particularly. Defects of anode baking furnace were gotten and modification of the anode baking furnace was provided.更多还原
