Numerical Investigation of Near-Tip Modifications for a Highly Loaded Low-Speed Rotor Under the Influence of Double Leakage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper numerically investigates the flow field in the tip region of a highly loaded axial low-speed compressor rotor. The rotor in focus is of a hybrid blade configuration, featuring a tandem profile in the mid-span ...
An Aero-Engine Disk Sizing and Weight Estimation Approach With Improved Temperature Profiles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the predesign phase of an aero-engine, interdisciplinary parametric studies are crucial for identifying an optimum engine. As innovative engine concepts emerge, it is essential to study trends aiming to minimize ...
Influencing Parameters of Tip Blowing Interacting With Rotor Tip Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design space of axial-flow compressors is restricted by stability issues. Different axial-type casing treatments (CTs) have shown their ability to enhance compressor stability and to influence efficiency. Casing ...
Numerical Calibration and Investigation of the Influence of Reynolds Number on Measurements With Five-Hole Probes in Compressible Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an investigation into the numerical and experimental calibration of a five-hole probe and effects of Reynolds number variations on the characteristics of the probe. The test object is a cone-type drilled ...
Numerical Investigation of the Interaction of a Circumferential Groove Casing Treatment and Near-Tip Modifications for a Highly Loaded Low-Speed Rotor Under the Influence of Double Leakage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Eckel et al. (2023, “Numerical Investigation of Near-Tip Modifications for a Highly Loaded Low-Speed Rotor Under the Influence of Double Leakage,” ASME J. Turbomach., 145(4), p. 041003) proposed using a convex-profiled ...
The Unsteady Shock-Boundary Layer Interaction in a Compressor Cascade—Part III: Mechanisms of Shock Oscillation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The shock-boundary layer interaction in transonic flows is known to cause strong unsteady flow effects that negatively affect the performance and operability of blade and cascade designs. Despite decades of research on the ...
Detailed Gaseous and Particulate Emissions of an Allison 250-C20B Turboshaft Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aviation is known to be one of the most significant contributors to air pollutants. This includes gaseous emissions, like carbon dioxide (CO2) and nitrogen oxides (NOx), and also particulate matter (PM), especially in the ...
