摘　　要：采用水力模型实验的方法对某公司设计的底吹炉内的流动过程进行研究,并利用VOF模型对所建立的水力模型进行数学建模。通过模拟结果和实验结果的对比,发现VOF方法能够描述底吹炉水力模型试验台中气体上升过程中所出现的气泡产生、长大和脱离的过程,为该方法向热态模型的推进提供依据。对比4种喷口结构对炉内流动过程的影响,对比结果显示弥散型结构的氧枪的搅拌面积更大,有利于底吹炉内的搅拌和化学反应过程高效进行,但其喷口处的压力波动更明显,对氧枪的寿命造成一定的影响。Water model was utilized to study the flowing process within a bottom-blowing furnace designed by some company, which was simulated by VOF model in the flowing process. The simulation and experimental results were compared. The results show that the VOF method can describe the formation, growing up and separation actions in the rising process, which can be a foundation of using the model to research the thermal process of the bottom-blowing furnace. According to the comparison of the influence on flowing process of four nozzles with different structures, it is indicated that a nozzle with disperse spouts can stir a larger zone. This disperse spouts are benefit to promote the process of stirring and reaction more efficiently, whereas the pressure fluctuation near the nozzle export is more obvious, which may affect the lifetime of the nozzle.
