초록 ▼

A flow directing assembly 24, 24a for a rotary machine 10 is disclosed. Various construction details are developed to decrease aerodynamic losses and promote the ease of design. In one particular embodiment, a concave region 58 of an end wall is employed to create convex wall regions 54, 56 upstream

대표청구항 ▼

A flow directing assembly for a rotary machine having a flowpath for working medium gases, the assembly including a first wall and a second wall which bound the flowpath and at least one pair of airfoils, each of which has a suction surface and a pressure surface, each of which has a leading edge and a trailing edge, and each of which extends across the flowpath leaving a rearwardly extending passage therebetween for working medium gases that is bounded laterally in a direction perpendicular to the rearward direction by the airfoils and bounded spanwisely by the walls, which comprises: the first wall having a first region extending rearwardly from the leading edge, the wall in the first region being convex toward the flowpath in the rearward direction from the leading edge, the first region extending laterally from the suction surface of the first airfoil to the pressure surface of the second airfoil; a second region extending forwardly from the trailing edge, the wall in the second region being convex toward the flowpath in the forward direction from the trailing edge, the second region extending laterally from the suction surface of the first airfoil toward the pressure surface of the second airfoil; a third region extending between the first region and the second region, the third region being concave toward the flowpath in the forward and rearward directions and extending laterally from the suction surface of the first airfoil to the pressure surface of the second airfoil.
