A theory is proposed for the formation and growth of particle dendrites on a collector placed in an aerosol or hydrosol stream. It is based on the interplay of two intrinsic properties of suspended particles: (i) their finite size and (ii) the randomness of the location of individual particles in the fluid stream. The results of simulations based on this theory resemble those obtained from experiments.
