Özet:

 


Pressure loss is one
of the important parameters in hydraulic engineering. Especially for the large
Reynolds Number, relative roughness has a significant effect on pressure losses
in annulus. In this study, water
flowing through rough and smooth concentric annulus for turbulent flow is
modeled using Computational Fluid Dynamics (CFD). CFD software based on the
finite element method predictions of pressure losses are compared with
experimental data obtained from the literature. The model predicts measured
frictional pressure gradient with an error less than ±15% in all cases.
Furthermore, pipe roughness influences on frictional pressure losses of water
are also examined for various pipe roughness values, inner and outer diameters
and Reynolds Number.  The analysis
results revealed that as the diameter ratio increases, the influence of
roughness on pressure gradient increases.
