The Influence Of Mixed Derivatives On The
Mathematical Simulation Of Pollutants Transfer
Author(s)
J.M. Sawicki & P. Zima
Abstract
Both turbulent diffusion and dissolved matter dispersion are anisotropic processes. From the
formal point of view this fact is expressed by the tensor form of the transfer coefficients. As a
result, mixed derivatives of concentration appear in the transport equations. However many
authors, for the sake of simplicity, neglect these derivatives. The paper deals with investiga-
tion of the influence of cross-derivatives, exerted on the results of calculations. Theoretical
and numerical analyses lead to the conclusion, that investigated terms are of great importance
and should not be neglected.
1 Governing equations
Two main versions of the dissolved matter conservation law are commonly used
for description of the mass transfer pr
