Abstract:
1. A method for suppressing the dynamic interaction among combustor cans in a gas turbine combustion engine, said method comprising the steps of: providing a plurality of consecutively arranged combustor cans for generating respective streams of combustion gases therein and collectively discharging the streams of combustion gases, the combustor cans defining a first group and a second group; providing a plurality of resonators, a first plurality of resonators coupled to the first group of combustor cans in the plurality of consecutively arranged combustor cans and a second plurality of resonators coupled to the second group of combustor cans; and selectively tuning the first plurality of resonators to suppress oscillations at a first frequency and tuning the second plurality of resonators to suppress oscillations at a second frequency different from the first frequency, such that one or more of out-of-phase and in-phase dynamic interactions of the streams discharged from adjacent combustor cans in the plurality of consecutively arranged combustor cans are suppressed.
