Non-contaminating flow visualization system |
摘要 |
A flow visualization system usable for clean rooms to determine the flow conditions that exist during manufacture, includes a non-contaminating source of a visible stream of a fog comprising water droplets which evaporaate and leave no residue. Steam is generated in a boiler and it passed over an interface with a cryogenic material to form a high density fog generator providing a highly visible fog that is neutrally bouyant and non-contaminating.
