Tubulence Combusion Modeling in the Gas Turbine Combustor

摘要

Numerical simulation was used to analyze three dimensional combustion flow for the annular combustor of a gas turbine. As to structure characteristic of gas Turbine combustor, the real combustion camber geometry with detailed features is represented. Numerical results for the reacting flow were obtained based on SIMPLE algorithm. the realize k -ε turbulence model, discrete ordinates method radiation model, non-adiabatic probability density distribution combustion model were app lied to predict the combustion process in the annular combustion. Simulated results showed that the flow and combustion performance of the three operating conditions accorded with design operating conditions. Through the numerical analysis, the design was optimized and improved, which provided useful base for design and engineering applications.
