PROPAGATION OF SUBSTANCE IN AN AXISYMMETRIC FILTRATION FLOW

The article considers the propagation of a substance in a cylindrical coordinate system in fi ltration fl ow. A common assumption is made that the dispersion coeffi cient is proportional to the transport velocity. Examples of exact solutions have been obtained supplemented with asymptotic representations. The possibility of using simple expressions to approximate a two-dimensional surface (a series of curves) that refl ects the solution of the problem is demonstrated.
