Mathematical Model of Velocity Distribution in Flow Field of Multijet for Large Scale Oxygen Lance
-
摘要: 基于對超音速自由射流速度衰減、分布參數的新的研究結果,在單股射流流場一階動量迭加的基礎上,采用以射流中心線偏轉所引起各點速度偏移和在多股射流相互作用區內引入抽引系數的兩步修正法,建立起多股射流流場速度分布的數學模型。模型計算結果能較好地描述多股射流流場速度分布的特征,與實驗結果較好符合.Abstract: A mathematical model for velocity distribution of multijet was developed based on the new relationship between two paraneters Kj and λj which describe the velocity distribution for the supersonic jet and the linear momentum superposition of single jet with two steps of correction, the inclination of jet centerline and the suction coeffcient. Calculated values are in good agreement with experiment results.
