3-D Numerical Simulation of Gas Turbine Combustor
نویسنده
چکیده مقاله:
This paper presents a numerical solution for a changing combustor geometry. The effects of the geometric change on the main parameters of the chamber are considered. For this purpose the original geometry and the new one are simulated numerically by a 3-D CFD code and the results are compared. Finally, comments are presented regarding this change. A model is used for turbulence modeling and an eddy dissipation model for reaction. Effect of thermal radiation is considered through solving an extra transport equation. The DO model is used to obtain radiation intensity.

The structural and aerodynamic performance of the air inlet volute has an important influence on the performance of the gas turbine. On one hand, it requires the airflow flowing through inlet volute as even as possible, in order to reduce the pressure loss, to avoid a decrease in the effective output power and an increase of the fuel consumption rate of the internal combustion engine which indi...
