ABSTRACT:
The resistance of a honeycombed structure to damage from asymmetric thermal shock occurring across its surface during use and formed with cells having anisotropic Young's moduli in the planes perpendicular the central longitudinal axis of each cell can be improved by varying the orientation of the anisotropic cells with respect to one another so as to minimize the number of such cells being oriented with an axis of maximum Young's moduli aligned with the direction of either the maximum temperature difference or maximum localized temperature gradient occurring across the cell. Improved heat recovery wheels can be formed by bonding together extruded cellular segments, most or all of which contain uniformly oriented, anisotropic square cells and by selecting and arranging the segments so that square cells are uniformly oriented with respect to one another in all segments across the face of the wheel except in those segments which are crossed by or adjacent to the two perpendicularly opposed diameters of the wheel which are paralleled to the sidewalls of the aforesaid, uniformly oriented square cells. In the latter subset of segments, the square cells are uniformly arranged with their diagonals parallel to the aforesaid perpendicularly opposed diameters. Certain exceptions are allowed for selecting the geometric form and orientation of the cells in the cellular segments at the very center of the wheel.
