Effect of nozzle spacing in the formation of primary and secondary deposits in multi-nozzle inertial impactors part I: Experimental study

摘要

Particle deposits in an inertial impactor stage can be classified as primary or secondary. The primary deposits are directly downstream of each nozzle. Secondary deposits can be in the form of a halo around the primary deposit or of straight-lines between adjacent nozzles. Certainly, these additional secondary deposits lead to a deviation from the theoretical efficiency curve in which only a single primary deposit existed and was considered.
