Abstract

Il procedimento consiste nel formare, all'uscita da un ugello di taglio (1), un getto centrale di liquido di taglio (14) e, simultaneamente, un getto concentrico di gas attorno al getto centrale di liquido, il getto di gas avendo una velocità superiore alla velocità del getto di liquido. Tipicamente, il liquido ed il gas hanno la medesima composizione, di preferenza ossigeno.
