Abstract

Different submodels used to simulate sticking of particles in deposits are reviewed. A new scheme for sticking of particles is proposed, according to which they stick in deposits if the generalizing viscosity of a particle and deposit surface does not exceed a certain value. The boundary conditions and a method used to calculate the generalizing viscosity are substantiated on the basis of experimental data.
