Modelling the Flow and Combustion in a Production Gas Turbine Combustor

  • Conference paper
Turbulent Shear Flows 5

Abstract

Most papers on flow modelling are concerned with simple laboratory flows. This paper demonstrates the application of current modelling methods to a production gas turbine combustor and demonstrates that the flow field, exit temperature and NOx emissions can be predicted to an acceptable accuracy even in such a complex flow. It is shown how the shape of the exit temperature pattern develops: any proposed modification to improve it can therefore be assessed prior to manufacture and test. Combustion chemistry is represented by a fluctuating equilibrium scheme, and the NOx formation rate is integrated over the fluctuations. The method uses a body-fitted orthogonal coordinate system which can be mapped into any axisymmetric internal flow region. The standard k — ε model used in the calculations is adequate for the flow field, the only alteration necessary being that the value of the effective Prandtl number for fuel be reduced from the value used in boundary layer flows.
