TANGENTIAL FRICTION ON THE WALL OF A CONTAINER WITH
A SPHERICAL CHARGE AND FLUID MOTION THROUGH THE CHARGE
V. V. Sorokin
UDC 532.507+546
Viscous tangential stress on the interior wall of
a container with a spherical charge, that develops in
filtration of an incompressible fluid through the charge
is investigated. Based on an analysis of an experimental
dependence of the dimensionless stress on the Reynolds
number, two critical Reynolds numbers are determined:
the first number corresponds to the beginning of an
abrupt drop in the stress, and the second number, to its
reaching a regime that is self-similar in velocity.
Comparison with the theory permits interpretation of the
effects of pseudoturbulence and turbulence, respectively.
