Dam-Breaking Problem
Experimental set-up
Dam-break wave generated by removal of a gate at
a bottom step Solid lines - theoretical
solution, dot lines - approximate solution (lines
1,2 - free surface, lines 3,4 - lower boundary of
the turbulent surface layer, water to the left
from the gate was coloured with ink)

(a)
(b)
Internal waves generated by a circular cylinder
oscillating in a linearly stratified fluid of
limited depth. The images are obtained with
syntetic schlieren technique For vertical (a) and
horizontal (b) oscillations waves degenerate into
1-st and 2nd modes, respectively. The oscillation
frequency is the same in both cases.

Laboratory of Filtration
Simulations of an invaded zone in borehole
drilling
The evolution of an invaded zone drilling in
water- and oil-saturated sand formations is
studied by mathematical modelling of
hydrodynamic processes in porous media filled
with a two-component fluid. The use of
hydrodynamic modelling to interpret
high- frequency electromagnetic logs makes it
possible to construct consistent geoelectric and
hydrodynamic models for formations with
different fluid saturations.
