THE ENERGY FLUX DIFFERENT STABILITY ESTIMATION OF HYDRAULIC FLOW IN A HORIZONTAL PIPELINE WITH LONGITUDINAL GROOVES NUMBER VARIATION
Abstract: The experimentally research
was governed to
estimate the external
(source) and internal
signal combined system without
separate each other.
Referring to that,
the Lumped Parameter
System (LPS) analytical modeling
method by Matko
et al (2001)
as looked as
possible is significance
and accurately toestimate
the internal pressure
or difference pressure
fluctuation of fluid
lines. By using
the LPS method were
known that the
hori z ontal fluid lines
dynamic system with longitudinal
grooves number variation
(in fractal geometry image) for which will be used as an object in this research are fulfilled
as a low frequency model class and
small gain pressure
fluctuation for every
measurement acquisition result
It’ s properly in the LPS modeling method, the hydraulic fluid lines should be looked as
a compressible fluid and over pass storage
of energy charging
so the response
is not only
affected by resistance
but also by
inductanc e and capacitance of
the fluid. The three fluid elements
respectively for a pipeline
length unit are
constant, have positive values
eventually and modified as a
function of the pipeline
hydraulic diameter. It ’s confirmed that the result
could be given
to predict the
locally linearly stability
character of the
fluid flow energy
fluxdifferent between upstream and downstream pipeline positions.
