A combustor including a first perforated layer including a first opening having a first diameter, wherein the first opening is configured to receive a flow of fluid including a fuel and air mixture; and impart a first rotational instability to the flow of fluid that is dependent on the first diameter; and a second perforated layer surrounding a combustion area, wherein the second perforated later includes a second opening having a second diameter, and wherein the second layer is located between the first layer and the combustion area. L'invention porte sur une chambre de combustion comprenant une première couche perforée comprenant une première ouverture ayant un premier diamètre, la première ouverture étant configurée pour recevoir un écoulement de fluide comprenant un mélange de carburant et d'air; et pour transmettre une première instabilité rotationnelle à l'écoulement de fluide qui dépend du premier diamètre; et une seconde couche perforée entourant une zone de combustion, la seconde couche perforée comprenant une seconde ouverture ayant un second diamètre, et la seconde couche étant située entre la première couche et la zone de combustion.
