Title: DETERMINATION OF THE PARTICLE SHAPE FACTOR USING CAUCHY’S THEOREM AND IMAGE ANALYSIS
Keywords: particle shape factor, Cauchy’s theorem, digital camera, image analysis

Abstract: The basis of this study for determination of particle shape factor is Cauchy's theorem, according to which the average projected area of randomly oriented convex particles is just one quarter of the average surface area of these particles. A large number of particles are photographed with digital camera on a flat surface and in ethanol-water mixture. By the means of experimental measurements and image analysis of different images, which are obtained through these two ways of photographing, are calculated two values of particle shape factor. All captured images are processed with commercial software ImageJ. The main aim is to achievement a random orientation of the particles and this is implemented through the photographing of the particles in a ethanol-water mixture.
