A mathematical model and a numerical method for calculating 
the dynamics of a fluid and the heat and mass transfer in it in a 
channel with penetrable walls are presented. Turbulent and transient 
flows in this channel were simulated on the basis of Navier-Stokes 
equations by the method of decreasing the rate of change in desired 
functions at certain nodes. The results of comparison of calculation 
and experimental data are presented.
