Abstract
Described is a stacked-plate apparatus having a plurality of plates stacked along an axis and having gaps between adjacent plates, each of which act as flow passageways for flow of fluid from a fluid inlet to a fluid outlet. Pairs of adjacent plates comprise one and optionally two lips, which extend axially into the flow passageway at the fluid inlet, thereby narrowing an inlet gap between the plates at the fluid inlet. The lips enhance the flow of fluid towards the fluid outlet of the flow passageway, for at least a working distance downstream thereof, as compared to a pair of adjacent plates that does not have the lips.
