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 ...

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 ...

Abstract: Abstract. Foreign object damage (FOD) poses a significant challenge to the durability of compressor blades in aero engines. Impacts from foreign objects can threaten structural integrity and increase maintenance costs. ...

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 ...

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 ...

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 ...

Abstract: Abstract. This article presents a detailed investigation into the 3-D flow field characterization and blockage effects in an open-jet probe calibration wind tunnel, utilizing a wide array of advanced measurement techniques. ...

Abstract: Abstract. This study numerically investigates passive and active flow control methods in a 2.5-stage, low-speed, highly loaded axial compressor with tandem stators. Two configurations are analyzed using unsteady Reynolds-averaged ...

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 ...

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 ...
