摘要： PROBLEM TO BE SOLVED: To provide a technology for improving the control and flame stability of the discharge of a turbomachine combustor. SOLUTION: The turbomachine includes a combustor assembly, a cap assembly attached to the combustor assembly, a center body 54 in the cap assembly, a wall 57 of the center body having a first end 59, a second end 60 and an intermediate portion 61, and an external turbulator member 75 in operable communication with the cap assembly. The external turbulator member is spaced from the wall to form a passage 78 defined by a gap between the wall of the center body and the external turbulator. The external turbulator member includes a step 88 positioned at the second end of the center body. The step defines a radial distance around the second end of the center body. The external turbulator member is formed having a step-to-gap ratio relative to the center body in a range of about 0.8 to about 1.2. COPYRIGHT: (C)2010,JPO&INPIT
