ShareVisualizing full-scale ventilation airflows.

Type of article: Article
Summary
Optical flow visualization involves no tracer particles, but passes a light beam through the flow and then examines this beam for distortions caused by temperature differences. Recently, a new approach to full-scale schlieren flow visualization became feasible. One wall of a large room is covered with a uniform "source" grid made of parallel black and white lines. At the other end of the room a lens forms an image of this grid on a sheet of photographic film placed in the "cutoff" position. This new instrument has only been in operation for about a year. Some early results are given next.
