Within the framework of similarity theory, a rather 
universal method is developed for generalizing experimental data on 
the hydrodynamics of a wide class of disperse systems with ascending 
motion of a gas. This method is based on use of the excess gas velocity 
u - u*t, which is a measure of the kinetic 
energy of the particles. Using this quantity, the hydrodynamic-similarity 
numbers Fr*t and J*s 
are formulated, which are generalized characteristics of such systems. 
Specific examples of applying this method are given.
