RISInvestigation of Nonaxisymmetric Endwall Contouring and Three Dimensional Airfoil Design in a 1.5 Stage Axial Turbine—Part II: Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is the second part of a twopart paper reporting on the increase in efficiency of a 1.5 stage axial test rig turbine with the use of nonaxisymmetric endwalls and 3D airfoil design. Contoured endwalls were developed ...
Investigation of Nonaxisymmetric Endwall Contouring and Three Dimensional Airfoil Design in a 1.5 Stage Axial Turbine—Part I: Design and Novel Numerical Analysis Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of the analysis of different 3D designs for the first stator and the rotor of a 1.5stage turbine test rig. A tangential endwall contouring for the hub and the shroud, a bowed profile stacking, ...
