Designing ,Implementing and Examining an Inertial Impactor as Aerosols Particle Size Separator.

Abstract

The Inertial Impactor is one of the important technique used for aerosols particles separation .For the aim of this work an inertial Impactor is designed and it is implemented in the local workshops. Generally ,the required cut off ratio and the efficiency of the Impactor are controlled by a number of aerodynamic factors. In this study the 50% cut off ratio is choose ,theoretically, to be at 1 µm . The implemented Impactor is examined by using an optical particle counter (Climate CI 500). The results show that the collection efficiency of the Impactor is nearly 100% for the particles of 5µm and larger.
