Mathematical Model of Velocity Distribution in Flow Field of Multijet for Large Scale Oxygen Lance

A mathematical model for velocity distribution of multijet was developed based on the new relationship between two paraneters K_j and λ_j 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.
