FLUID FLOW MODIFICATION APPARATUS

摘要

A fluid flow modification apparatus has a plurality of flow modification elements each having a first surface portion against which a fluid (F) can flow and a second surface portion along which the fluid (F) can flow. The elements are arranged in a number of sets. A first set of elements comprises a plurality of fluid flow modification elements with a first surface portion. A second set of elements comprises a plurality of fluid flow modification elements with a first surface portion having a surface area different from that of the first set. The first set of elements includes first and second types of fluid flow modification elements. The depth of the second surface portion is different from the depth of the second surface portion.
