Spreadsheet calculations of jets injected normal to a crossflow in a rectangular duct from opposed rows of slots slanted at 45°

The primary conclusion in this paper is that the best mixing configuration for opposed rows of slanted slots, at any downstream distance, is a parallel staggered configuration. Although distributions from “crossed” slanted slots are similar to those from parallel configurations at particular locations, results for crossed slots are highly dependent on downstream distance and are no better than parallel slots at locations where they are similar and are worse than parallel ones at other distances.
