Paper Abstract

The thermal emission phenomena in aerosol clouds is strongly related to the thermo-optical properties of each particle in the cloud. For this reason, we have studied the optical properties of a single particle, using the principle of radiative pressure levitation, with an Ar (or CO2) Laser. The particles have a diameter in the 5-80 micrometers range, and are heated at high temperatures when illuminated by a laser beam. These temperatures have been determined by optical pyrometry, on glass particles coated with aluminum or gold; radiance temperature up to 1000 K or more have been obtained. The general applications of this study can be found in the field of radiative heat transfer in liquid or solid rocket particles.
