Description

Proposes a method based on tracer gas techniques for determining interzonal airflows and effective volumes in a multizone enclosure. The method uses a single tracer gas to disturb the zones. Uses a state-space formulation to model the multizone system. Uses the concentration data in combination with a recursive least-squares identification algorithm to determine all of the interzonal airflows and effective volumes. Presents experimental results which indicate that the single-gas technique was able to estimate the interzonal airflows and effective volumes of the test facility to within 10% in most cases.

KEYWORDS: Tracers, air flow, experiment, accuracy, algorithms, calculating
