Study on Gas Turbine Combustor Cooling Calculation

45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009
The results of a comprehensive study on gas turbine combustor liner cooling calculation method are reported. Based on the present study, the radiation from non-luminous gases shall be calculated by new method, which is significantly different from the equation commonly available. Under high pressure the emissivity of non-luminous combustion gases shall

Pressure measurements in a scramjet combustor with film cooling

21st Aerodynamic Measurement Technology and Ground Testing Conference, 2000
Experiments have been performed on a 500 mm long cylindrical scramjet, combustor in the T4 free piston shock tunnel at The University of Queensland. Four different fuel injectors designed to provide varying slot equivalence ratios were tested at a nominal freestream Mach number of AA and stagnation enthalpy of 5.8 MJ/kg.

A Review of Impingement Jet Cooling in Combustor Liner

Volume 5C: Heat Transfer, 2018
Impingement jet cooling is a promising cooling method in modern dry low emission combustor because of its high local heat transfer coefficient. This paper investigates the recent research progress on impingement jet cooling in combustor liner. Firstly, the different flow characteristics in the different impingement jet flow regions are described. Then,

Automated cooling design methodology for combustor walls

36th AIAA Aerospace Sciences Meeting and Exhibit, 1998
An automated cooling design procedure for aircraft engine combustors has been developed which uses a converged CFD flow solution and produces a detailed temperature distribution in the liners, dome, etc. of a combustor. The output of the automated procedure is the following: a detailed wall temperature and heat flux distribution; arrangement of ...

Emissions from and within a Film-Cooled Combustor

Combustion Science and Technology, 1975
Abstract Internal measurements of carbon monoxide, unburned hydrocarbons and nitric oxide are reported for different axial and radial positions within an Allison T-56 film-cooled liner and used to construct a flow and combustion model for the T-56 liner. In addition, pollutant concentrations were measured at the combustor exit plane for both liquid and

Modelling and Measurements of Combustor Cooling Tile Flows

Volume 2: Turbo Expo 2003, 2003
Pressure to reduce available cooling air in modern combustors has driven recent interest in cooling technology based on double-skinned combustor liners, i.e. tiles containing multiple pin-type pedestals to enhance heat transfer. The design of such systems is, however, hampered by the multiplicity of parameters needing optimisation: feedhole ...
