Abstract

A turbulent jet of air was seeded with both particles and a vapour. An excimer pump dye laser excited visible fluorescence from the biacetyl vapour and Mie scattering from the micron size particles. It was possible to measure the simultaneous scattering from both phases by using interference filters to separate the signals. It was found that the biacetyl vapour provides an adequate tracer for measurement of the concentration field in a turbulent flow. Futhermore, the feasibility of making simultaneous concentration measurements of two phases in a turbulent flow was demonstrated.
