The spray characterization is very inportant to understand the effect of NO<SUB>x</SUB> and Soot concentrations in the exhausted gas of spray combustion. Under these circamstances, it is nesessary to develop and establish to method of simultaneously measuring the diameter (size), number density and velocity distribution of the fuel droplets in a non-contact way using some means which can enhance the time and space resolution in atomizing group.<BR>It is difficult to determinate of coarse aerosol size, as it is obvious from the caluclated results of light scattering theory by G.Mie However, in this report, these methods have made it possible to measure with the ratio of integrated values the scattered light intensities over the two domains (plane angles) .<BR>This method has been utilized for determination of size in actual nozzle, after examining the standerd particle size by Ultra Sonic Humidifier.
