RISA Sector-Cascade Test Rig for Measurements of Heat Transfer in Turbine Center Frames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The turbine center frame (TCF) is an inherent component of turbofan aircraft engines and is used for connecting the high-pressure turbine (HPT) to the low-pressure turbine (LPT). Its position immediately downstream of the ...
Vane–Probe Interactions in Transonic Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, a numerical investigation of the effect of a miniaturized five-hole probe downstream of a transonic low-pressure turbine vane row is presented. First, a numerical calibration of the probe was performed in ...
The Influence of Combustor Hot Streaks on the Aerodynamic Performance of a Turbine Center Frame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the influence of combustor temperature non-uniformities on modern engine turbine center frames (TCFs). Due to their position in an engine, coupled with the trends of more aggressive designs, increased ...
The Influence of Purge Flow Parameters on Heat Transfer and Film Cooling in Turbine Center Frames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The imperative improvement in the efficiency of turbofan engines is commonly facilitated by increasing the turbine inlet temperature (TIT). This development has reached a point where also components downstream of the ...
Experimental and Numerical Comparison of Two Turbine Vane Frame Designs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental study supported by numerical simulations of the performance of two turbine vane frames (TVFs) at various purge and TVF inlet swirl conditions representing both on- and off-design operations. ...
Measurements and Modeling of Ingress in a New 1.5-Stage Turbine Research Facility
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In gas turbines, hot mainstream flow can be ingested into the wheel-space formed between stator and rotor disks as a result of the circumferential pressure asymmetry in the annulus; this ingress can significantly affect ...
Influence of Leakage Flows on Hot Gas Ingress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the most important problems facing gas turbine designers today is the ingestion of hot mainstream gases into the wheel-space between the turbine disk (rotor) and its adjacent casing (stator). A rim seal is fitted ...
Re-Ingestion of Upstream Egress in a 1.5-Stage Gas Turbine Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In gas turbines, rim seals are fitted at the periphery of stator and rotor discs to minimize the purge flow required to seal the wheel-space between the discs. Ingestion (or ingress) of hot mainstream gases through rim ...
Design and Testing of a Rig to Investigate Buoyancy-Induced Heat Transfer in Aero-Engine Compressor Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The change in compressor blade-tip clearance across the flight cycle depends on the expansion of the rotor, which in turn depends on the temperature and stress in the disks. The radial distribution of temperature is directly ...
