Paper Abstract

Many existing techniques for aerosol characterisation are based on the utilisation of their optical properties, but have a major disadvantage in so far as the results tend to be dependent on the signal processing techniques employed. A direct measurement technique has many advantages particularly in terms of ease of validation and verification of results. An innovative method for the characterisation of aerosols has been developed using a synchronised metal vapour laser light source and a High speed cine camera. The use of an optical fibre and flexible borescope enables the image capture of aerosols generated in a number of environments. Data has been collected in the form of size distribution, velocity and trajectory. Data on collisions has also been collected. Example studies have included the bio-hazard aerosols generated during industrial processing and the aerosol generated from a two phase release of liquid petroleum gas.
