Practical Application of 3-D CFD Methods to Gas Turbine Combustors

摘要

The objective of the application of three dimensional Computation Fluid Dynamics(CFD) methods is to assist the design and development process by proving reasonable predictions of combustor flows at a reasonable cost and in a reasonable time. Some of the features that have to be considered in a practical CFD system, are described and some idea of the sort of problems being tackled on the gas turbine industry using these methods is given. Specifically the following are covered: mesh generation techniques, boundary conditions, turbulence modeling, combustion modeling, output display, combustor flow applications, some other geometries of interest, future developments.
