Abstract
A seal includes two layers, each layer including a base and fingers extending from the base. The fingers are separated by slots and the fingers include orifices. The slots of each layer are laterally spaced apart from each other. The orifices of one of the layers are partially overlapped by the orifices of the other layer so that the areas of the partially overlapped orifices extend beyond the areas of the overlapping orifices.
