摘要: A damper for a combustor assembly (3) of a gas turbine assembly (1) is provided with:
at least two damping volumes (32, 35) defined by respective damping bodies (31, 34); the damping volumes (32, 35) being interconnected in fluidic communication;
at least one perforated connecting plate (36) connecting the two damping volumes (32, 35);
at least one perforated end plate (38) configured to connect at least one of the two damping volumes (32, 35) with a combustion chamber (16; 14) of the combustor assembly (3);
the perforated connecting plate (36) and the perforated end plate (38) being provided with a plurality of openings (42);
the openings (42) being dimensioned so as to operate in a low Strouhal regime according to the following formula ω ⋅ R H / Ub 0 , 5 wherein:
• ω is the angular frequency correlated to the frequency to damp according to the following relation ω=2πf;
• R H is the equivalent radius of one of the openings (42);
• U b is the velocity of the flow through one of the openings (42). -
