Experiment on outlet temperature field of a gas turbine combustor

  • The influence of aperture ratio and center distance of a gas turbine combustor mixing system on outlet temperature field was studied experimentally.Experimental results indicate:the outlet temperature distribution coefficient reduces gradually with the increase of aperture ratio.But too large aperture ratio will lead to partial obstruction and also hot spot temperature rise;aperture ratio does not change the radial temperature distribution curve shape,but only bring about shift of its position.Relative center distance and the radial temperature distribution coefficient have a strong correlation,too large (more than 0.33) or too small (less than 0.29) is not helpful for dilution.Relative center distance of 0.31 and aperture ratio of 0.32 are basically reasonable in this case.
