Abstract
In one embodiment, a fluid flow channel includes a first part and a second part connected to and positioned downstream from the first part such that fluid can flow from the first part to the second part. The first part has opposing sidewalls, a floor extending between the sidewalls, and a ceiling extending between the sidewalls. The ceiling of the first part slopes upward in an upstream direction or the sidewalls taper in toward one another in a downstream direction, or both. The second part has opposing sidewalls and a ceiling extending between the sidewalls. The ceiling of the second part slopes upward in an upstream direction.
