Abstract
Combustion instability of synthetic gas in a partially-premixed combustor has been numerically investigated by varying H2 percentage of the fuel composition. During predictions with utilization of a lumped network code, the effects of different flame transfer function (FTF) models, which include the 2 order filter model and the state space model, and acoustic boundary conditions have also been investigated. The predicted results quite agree well with the corresponding experimental ones.
