TITLE: Hydraulic shock in a deformed pipe line
PERIODICAL: Leningrad. Universitet. Vestnik. Seriya matematiki,
mekhaniki i astronomiip no- 4P 1961, 93 - 102
TEXT: The hydraulic shock is consideredp due to the deformation
of the pipeline by pre'ssure and inertia forces of the fluid on dis-
placement of the pipeline. Similar problems arise in the study of
dynamic processes in cooling systems of engines# the effect of
shock-waves on pipelines# etc. Basic equations: As an example, a
cylindrical pipe (the combustion-chamber of an engine) with an en-
velope (shell) is considered; the cooling-liquid flows between pipe
and envelope (Fig. I). The increased pressure inside the chamber
leads to deformation of the pipewalls and the appearance of addi-
tional velocity components. Neglecting friction and the geometric
head, the system of equations which determines the unsteady fluid
flow in a system of coordinates linked with the pipep is
