Abstract

A method for calculating the motion characteristics of fractal-like aggregates based on the use of gas-kinetic results for homogeneous spherical particles is presented. The essence of the technique consists in replacing the real fractal aggregate by equivalent sphere with the mobility radius and in approximation of density and thermal conductivity of particles by their effective values. This method confirmed its efficiency in comparison with known experimental data.
