An investigation of flush off-takes for use in a cooled cooling air system

  title={An investigation of flush off-takes for use in a cooled cooling air system},
  author={P. Elango and Alastair Duncan Walker},
The design and evaluation of off-takes has traditionally focused on increasing ram pressure recovery with little consideration given to flow uniformity. Preliminary studies on a proposed cooled cooling air system for a large aero gas turbine indicated that the offtake represented a weak point in the design with the non-uniformities it generated negatively affecting system performance. High levels of diffusion and a uniform flow are required to minimise loss and to maximise the effectiveness of… Expand
Numerical Study of the Flow Uniformity Inside the High-Pressure Side Manifolds of a Cooled Cooling Air Heat Exchanger
Abstract To maintain efficiency in advanced aero-engines, it is crucial to set high limits for the Operating Pressure Ratio (OPR) and Turbine Entry temperature (TET). This can be achieved using aExpand
Transient Performance Analysis of an Aero Gas Turbine Cooled Cooling Air Heat Exchanger
Aviation faces several challenges to maintain growth while adapting to an environmentally viable footprint. Increasing efficiency, which in the past induced a steady rise in the turbine entryExpand
Aerodynamic design of a cooled cooling air system for an aero gas turbine
This paper examines the aerodynamic design requirements of a cooled cooling air system for a large, high by-pass ratio, high overall pressure ratio aero-engine. This can be broken into aerodynamicExpand


Performance Improvement of Flush, Parallel Walled Auxiliary Intakes by Means of Vortex Generators
Results showed a performance improvement of between 35% and 40% as a result of the application of the vortex generators, with the best result obtained when the VGs were closest together, but not so close as to cause ingestion of the vortices. Expand
Impact of a Cooled Cooling Air System on the External Aerodynamics of a Gas Turbine Combustion System
The trend for higher overall pressure ratios means that turbine entry temperatures are continually increasing. Furthermore, the development of lean, low-emission combustion systems reduces theExpand
Variation of Flow Control Configurations to Improve Submerged Inlet Uniformity
A ∞ow control study was initiated upon a generic submerged inlet to determine whether discrete blowing could be efiective in eliminating the boundary layer deflcit created in the throat and thereforeExpand
Theoretical Investigation of Submerged Inlets at Low Speeds
The general characteristics of the flow field in a submerged air inlet are investigated by theoretical, wind-tunnel, and visual-flow studies. Equations are developed for calculating the laminar andExpand
