Impact Characteristics of Coherent Supersonic Jet

Supplying oxygen into the molten bath via impinging jets is a main feature of the EAF steelmaking process (Lee and Sohn in JOM 66:1581–1594, 2014; Wei et al. in Metall and Mater Trans B 47:3066–3079, 2016). In modern EAF steelmaking, both the coherent supersonic jet and the conventional supersonic jet have been widely used (Alam et al. in Metall and Mater Trans B 41:1354–1367, 2010; Wei et al. in J Iron Steel Res Int 23:997–1006, 2016).
