Abstract The primary purpose of this paper is to show that the criticisms by Tsotsas and Schlunder (1988) of an earlier paper (Gunn, 1969) are based upon elementary mathematical errors of the part of Tsotsas and Schlunder. A summary of experimental data on axial dispersion in liquids and gases shows that the dependence of the axial dispersion coefficient upon the Schmidt group predicted by Tsotsas and Schlunder is not observed despite the large number of emperical factors in their expressions… CONTINUE READING
