摘要：

A numerical analysis of a low NOx partially premixed burner for industrial gas turbine applications is presented. In the first part the mixing inside a double annular counter-rotating swirl nozzle where the fuel is injected in a transverse jet configuration is studied. Standard k - epsilon model and Two variable Schmidt number models were assessed in order to find a reliable configuration able to fit the available experimental profiles. Resulting profiles are used to perform reactive simulations of the experimental test rig, where NOx, CO measurement were available Results are compared in terms of NOx concentration at the outlet with experimental data.
