Abstract
An evaporation process of micro droplets behind a shock wave has been investigated by using light scattering and light extinction method. A specific spatial filtering method was adopted in the experiment. Photographs of flow field was obtained in two dimensional image with the filtering method. Obtained data were processed by a computer. The variation of droplet radius and the number density were estimated from these data. Experimental results were compared with the one dimensional numerical analysis. Experimental results show a good agreement with computational one.
