A method for operating a vacuum vessel with a coherent jet wherein vacuum conditions are established within the vessel and an anchored or attached flame envelope resulting from subsonic velocity fuel and oxidant is provided around at least one supersonic gas stream. Another aspect of the invention is a method for forming and maintaining a coherent gas jet within a vessel comprising injecting gas in a gas stream at a supersonic velocity from an injection device into the vessel wherein vacuum conditions are established, providing fuel and oxidant at a subsonic velocity into the vessel around said gas stream, and combusting said fuel and oxidant to form a flame envelope around said gas stream to form and maintain said gas stream as a coherent gas jet.

L'invention concerne un procédé d'exploitation d'une enceinte à vide, dans laquelle des conditions de vide sont créées, pour former un jet cohérent ainsi qu'un panache accroché, résultant de l'injection à vitesse subsonique du combustible et de l'oxydant, autour d'au moins un flux gazeux supersonique. Un autre aspect de l'invention concerne un procédé de formation et de maintien d'un jet gazeux cohérent dans une enceinte. Ce procédé consiste à: injecter, au moyen d'un dispositif d'injection, un gaz contenu dans un flux gazeux à une vitesse supersonique dans une enceinte dans laquelle des conditions de vide sont créées; fournir, dans l'enceinte, un combustible et un oxydant à vitesse subsonique, autour du flux gazeux; et enfin, provoquer la combustion du combustible et de l'oxydant pour obtenir un panache autour du flux gazeux, et par conséquent, former et maintenir le flux gazeux sous forme de jet gazeux cohérent.
