Abstract

L'invention a pour objet une structure de filtration de gaz chargés en particules en nid d'abeilles comprenant un ensemble périodique de canaux (21, 22) adjacents, ladite structure étant telle qu'en coupe transversale chaque face interne (24) d'un canal d'entrée (21) épouse la forme d'un arc de cercle interne possédant un rayon Ri ayant une valeur finie et un centre Ci, chaque face externe (25) du canal d'entrée (21) épouse la forme d'un arc de cercle externe possédant un rayon Re et un centre Ce, et pour chaque paroi (23), le centre Ci du cercle interne est situé à une distance d non-nulle du centre Ce du cercle externe.The subject of the invention is a structure for filtering gas charged with honeycomb particles comprising a periodic assembly of adjacent channels (21, 22), said structure being such that in cross section each inner face (24) of an inlet channel (21) is in the form of an inner circular arc having a radius Ri having a finite value and a center Ci, each outer face (25) of the inlet channel (21) is in the form of an outer circular arc having a radius Re and a center Ce, and for each wall (23), the center Ci of the inner circle is located at a non-zero distance d from the center Ce of the outer circle.
