Ve. Kutsakova et Sv. Frolov, DISTRIBUTION-FUNCTIONS OF SUBSTANCE WITH RESPECT TO RESIDENCE TIME INITS MOTION IN INFINITE OR SEMIINFINITE CHANNELS, Russian journal of applied chemistry, 69(7), 1996, pp. 1083-1084
The problem is solved concerning the residence time distribution of pa
rticles that drift and simultaneously mix following the diffusion law
in infinite and semiinfinite channels. The derived formulas are applie
d to analysis of experimental data on particle motion in apparatus wit
h a directed fluidized bed.
