Experimental Investigation of Pressure Side Flow Separation on the T106C Airfoil at High Suction Side Incidence Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this work is to study the influence of a pressure side separation bubble on the profile losses and the development of the bubble in the blade passage. For the experimental investigations, the T106 profile ...
Boundary Layer Control on a Low Pressure Turbine Blade by Means of Pulsed Blowing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current work investigates the performance benefits of pulsed blowing with frequencies up to 10 kHz on a highly loaded low pressure turbine (LPT) blade. The influence of blowing position and frequency on the boundary ...
Investigation 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, ...
Loss Mechanisms of Interplatform Steps in a 1.5-Stage Axial Flow Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the detailed steady and unsteady numerical investigations of a 1.5-stage axial flow turbine are conducted to determine the specific influence of interplatform steps in the first stator—as caused by deviations ...
Blade–Row Interactions in a Low Pressure Turbine at Design and Strong Off Design Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a joint project between the Institute of Aircraft Propulsion Systems (ILA) and MTU Aero Engines, a twostage low pressure turbine is tested at design and strong offdesign conditions. The experimental data taken in the ...
On Turbulence Measurements and Analyses in a Two-Stage Two-Spool Turbine Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the experiment in turbulence research is of very high importance for evaluating turbulence hypothesis, turbulence measurements were carried out in a two-stage two-spool transonic turbine test rig at the Institute for ...
