Abstract

''PROCESSO E APARELHAGEM PARA ESTABELECER UMA CORRENTE DE GáS PRINCIPAL COESA DE ELEVADA VELOCIDADE, E, PROCESSO PARA INJETAR GáS DENTRO DE UM LìQUIDO" Um sistema para estabelecer e manter um jato de gás supersónico coesa, efetivo com um gás quer inerte quer oxidante, empregando um bocal covergente/divergente para estabelecimento de uma velocidade supersónica inicial não prejudicial, e um envelope de chama de três camadas definidas se movendo mais lentamente coaxial com o jato para manutenção efetiva da velocidade supersónica. A invenção é particularmente útil para a injeção de gás dentro de uma poça de líquido.
