Kinetic modeling of composite particles coagulation

The paper considers the formation kinetics due to coagulating behaviour of composite particles, represented by a mixture of different materials. New kinetic equations are defined which provide correct account of every formation stage of composite particles and are subject to direct numerical solution. Analytical solutions are obtained for some simple cases. Generally, self-similar distributions are used to analyse the solutions for their asymptotic behaviour. A method is developed to solve the coagulation kinetic equation of composite particles, with its validity shown by some test problems.
