Interrelation of optical and microstructural characteristics of mists

This work was undertaken to explain a discrepancy between values of the absolute attenuation coefficient calculated using the microstructure data from a flow collector, and those from measurements by a photometer.On the basis of a great many experiments, it has been demonstrated that these discrepancies were caused by a systematic understating of the value of absolute droplet concentration determined by the flow collector. It was also shown that the flow collector, while distorting the absolute droplet concentration data under the given conditions, determines quite accurately the drop size distribution function.
