ABSTRACT:
A measuring device for determining average mass flux, penetration rate, and droplet size both spatially and temporarily in a spray pattern from a spray nozzle. The measuring device includes a movable mounting arrangement that securely positions a spray nozzle such that it can emit a spray pattern along a generally vertical axis. A collection means consisting of a series of collection tubes is positioned below the mounting arrangement such that the collection tubes collect a portion of the spray pattern emitted from the spray nozzle. Each collection tube includes a gas relief opening such that the spray droplets can freely enter the collection tubes. A shutter mechanism is movably positioned between the spray nozzle and the collection means. The shutter mechanism is operated in a timed relation to the pulsing of the injector, such that the shutter mechanism selectively isolates a portion of the spray pattern and the only isolated portion of the spray pattern reaches the collection tubes. In this manner, the measuring device can selectively determine the mass flux distribution in a spray pattern a desired amount of time after the start of injection.
