RISComparison of the Aerodynamics of Acoustically Designed Exit Guide Vanes and a State of the Art Exit Guide Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within previous EU projects, possible modifications to the engine architecture have been investigated, which would allow for an optimized aerodynamic or acoustic design of the exit guide vanes (EGVs) of the turbine exit ...
On the Influence of an Acoustically Optimized Turbine Exit Casing Onto the Unsteady Flow Field Downstream of a Low Pressure Turbine Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern low pressure turbines (LPT) are designed in order to fulfil a various number of requirements such as high endurance, low noise, high efficiency, low weight, and low fuel consumption. Regarding the reduction of the ...
Rim Seal Flow Analysis Through a Novel Technique in a Highly Instrumented Two Spool Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study introduces the first application of a sparsity-promoting linear regression technique to analyze the flow behavior within the rim seal region between the rotor and stator disks in a highly instrumented ...
Experimental Investigation of Turbulence Inside an Annular Turbine Exit Guide Vane Cascade With Unsteady Wakes and Purged Cavity Using Constant Temperature Anemometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The total efficiency of jet engines can be increased by implementing recuperative systems. These systems need an increased fluid total temperature downstream of the low-pressure turbine (LPT). Thus, a method is ...
