Entry- (5-7) and exit- (8) channels are arranged in relation to each other such that gas filtered by one inlet channel enters exit channels adjacent to it. Entry and exit channels (5, 6, 7; 8) are delimited by mutually-perpendicular parallel walls forming first and second grids (seen in cross section), with respective differing spacings (D1 and D2), forming bi-periodic wall distributions. The spacing is defined by D1 = l(1+b) and D2 = l(1-b), with l and b being constants where b = 0.2-0.8. Entry channels and exit channels are delimited by non-planar wall sections, such that the overall volume of inlet channels is increased at the expense of that of the exit channels. |
