Comparison of results for model B and for CFD model.
Results obtained from model B and model CFD coded in Comsol package were compared as previously described in RESULTS AND DISCUSSION section. Results are presented in Table B1 and in Fig. B1. The dispersion coefficients values are similar, the average difference is about five percent. However statistical indicators presented in Table B1 show that the method based on transfer function (model B) fits experimental result better than CFD model. The same relation is visible in Fig. B1, as well. Lines that are generated by model B lies closer to the experimental lines than those generated by model CFD. It confirm the conclusion formulated in the main part of the paper, that models based on transfer function can be recommended as the alternative for models coded using CFD programs.
