Abstract

A fluid-flow-modification plate comprises a monolithic body, having an inlet-side surface and an outlet-side surface, a first passage, a second passage, a third passage, and a fourth passage. The first passage, the second passage, the third passage, and the fourth passage each extend between the inlet-side surface and the outlet-side surface. The first passage and the second passage intersect each other at a first intersection boundary. The third passage and the fourth passage intersect each other at a second intersection boundary. The first passage and the third passage do not intersect each other. The second passage and the fourth passage do not intersect each other. The first-passage-inlet-opening perimeter boundary has only two points of intersection with the fourth-passage-inlet-opening perimeter boundary. The second-passage-outlet-opening perimeter boundary has only two points of intersection with the third-passage-outlet-opening perimeter boundary.
