Optimisation of Combustor Wall Heat Transfer and Pollutant Emissions for Preliminary Design Using Evolutionary Techniques

摘要

This paper presents the concept and application of a design optimisation toolbox, basedupon evolutionary techniques, for the preliminary design of a gas turbine combustor.The toolbox has been designed to interface with existing analysis packages and toperform optimisation in parallel over a heterogeneous network of workstations. Theoptimisation capabilities of the toolbox are demonstrated for gas turbine combustordesign by automatically attaining twenty-two performance targets in a combustor designwhilst performing minimisation of wall cooling flow and NOx emissions.
