SYSTEM FOR SUPPLYING PROXIMATE TURBULENT GAS JET AND COHERENT GAS JET

摘要

PROBLEM TO BE SOLVED: To provide a system which can effectively supply both a coherent gas jet and a turbulent gas jet, both of which are proximate to each other, into an injection volume. SOLUTION: This system which supplies a gas into the injection volume in the form of one or a plurality of coherent gas jets which are close to one or a plurality of turbulent gas jets forms the coherent gas jets in a mold by using a frame envelope before the coherent gas jets are passed to the injection volume to which the turbulent gas jets are directly passed.
