EQUALIZATION OF THE CONCENTRATION OF A SCALAR IMPURITY IN A FLOW-TYPE CHAMBER

Experimental and theoretical investigations of the time 
of equalization of the concentration of an impurity in a rectangular 
flow-type chamber have been carried out. It has been shown that the 
process of equalization of the concentration with time is exponential 
in character. The characteristic equalization time has been computed 
using the theory of turbulent diffusion. Theoretical results describe 
experimental regularities with an accuracy of about 10%. The value 
of the coefficient of turbulent diffusion for different configurations 
of flows in the chamber has been obtained from a comparison of experimental 
and calculated results.
