Abstract
Particle pollution is the term for a mixture of solid particles and liquid droplets
suspended in the ambient air. Research studies have associated exposure to
elevated levels of these particles in the air with damaging health effects. Now,
there is an increased regulatory pressure to demonstrate continuous compliance
with microscopic particulate mass emission limits. This paper describes the
various settings of an experimental project aimed at developing the principals of
a non-intrusive device, using the Particle Image Velocimetry (PIV) laser
technique, for online measurement of dust particulates. This study will allow the
assessment and analysis of small particulates suspended in a slow moving flow
medium (the simulation is performed in water), and to study the various aspects
affecting particle size measurements.
Keywords: environmental control, laser application, PIV technique, particle
measurement, emissions monitoring.
1 Introduction
Particle pollution (also called Particulate Matter (PM)) contains a mixture of
microscopic solids particles or liquid droplets. It includes \“inhalable coarse
particles,” with diameters ranging from 2.5 micrometers (µm) to 20 µm and \“fine
particles” with diameters equal to or smaller than 2.5 µm. The size of particles is
directly linked to their potential for causing health problems. Small particles less
than 20 µm in diameter pose the greatest problems, because they can get deep
