Similarity of transport processes in disperse systems with suspended particles

On the basis of account for special features of hydrodynamics of disperse systems with suspended particles within the framework of the dimensional theory we obtained a system of dimensionless groups (35) which describes similarity of transport processes. System (35) involves new criteria Frt*=(u−ut*)/gH, Js*=Js/ρs(u−u*t) which involve an excess superficial gas velocity u−ut* and are important generalized characteristics of convective motion of particles. Typical examples of use of system (35) for generalization of experimental data are presented.
