RISA New Alternative for Reduction in Secondary Flows in Low Pressure Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a new flow mechanism for the reduction in secondary flows in low pressure turbines using the benefit of contoured endwalls. The extensive application of contoured endwalls ...
Endwall Boundary Layer Development in an Engine Representative Four-Stage Low Pressure Turbine Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research by (“ Influence of the State of the Inlet Endwall Boundary Layer on the Interaction Between the Pressure Surface Separation and the Endwall Flows,” Proc. Inst. Mech. Eng., Part A, ...
Minimizing Sampling Loss in Trace Gas Emission Measurements for Aircraft Engines by Using a Chemical Quick-Quench Probe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the development and testing of a gas sampling probe that quenches chemical reactions by using supersonic expansion and helium dilution. Gas sampling probes are required for ...
Design Parameters for an Aircraft Engine Exit Plane Particle Sampling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The experimental data and numerical modeling were utilized to investigate the effects of exhaust sampling parameters on the measurements of particulate matter (PM) emitted at the exit plane of ...
