Abstract
A plate and facing assembly (10), including a plate (12) and a facing (14) mounted on the plate. The facing (14) defines a substantially circular outer groove (20) and a substantially circular inner groove (22) spaced from the outer groove. The facing (14) defines a waved groove (24) between the outer and inner grooves (20, 22). The outer, inner and waved grooves (20, 22, 24) are interconnected by a plurality of flow grooves (28, 30, 32) defined by the facing (14). The grooves (20, 22, 24) interact to channel the flow of fluid.
