18-1 EXTRAGEREA HIDROGENULUI SULFURAT SI RENATURALIZAREA MĂRII NEGRE

HYDROGEN SULPHIDE EXTRACTION AND
BLACK SEA NAURALIZATION
One presents an original method and installation to naturalise the
deep waters of the Black Sea, menaced to be in any decades a death sea.
One gives a theoretical part for the applying proposed installation and
one presents the multiple advantages of the proposed method and installation,
which are not only environment friendly, but also endowed with many
renewable energies and valuable materials achievements.
Cuvinte cheie: renaturalizarea Mării Negre, extragerea hidrogenului

22-1 VISCOUS LIQUID THREE DIMENSIONAL FLOW THROUGH THE TURBO-MACHINES LABYRINTHS

In this paper we shall present such the numerical solving as the
experimental test of the viscous liquid three dimensional flow through the
clearance with and without baffle plate of the hydraulic turbo machine
labyrinths, considering the ring curvature by using the flow equations written in
the cylindrical trihedral coordinates.
We present also the stability of the numerical solution and the specific
boundary conditions to the posed problem, as well as the installation to
visualize the appearance of Sir Geoffrey Taylor’s whirls.
