Cette étude vise à comprendre et quantifier l’influence des structures cohérentes sur les petites échelles turbulentes dans un jet annulaire à fort rapport de diamètres. Ce type de jet est représentatif des géométries de type ''bluff-body'' largement utilisées en combustion. On s’intéresse, dans un cas d’un jet faiblement chauffé, à l’évolution axiale des quantités moyennes de vitesse et de dissipation de l’énergie cinétique, ainsi que des quantités moyennes de scalaire passif associées
