At the present paper, a conventional 90
turbulent incompressible airflow was numerically studied. The
loss coefficient attributed to the elbow resistance was
determined at different Reynolds number with the main
objective of validate the numerical tool.
that these effects aren’t restricted to the elbow outlet but can
be captured at a considerable downstream distance in
agreement with the work of Gallegos
This study represented a preliminary step to analyze duct
fittings encountered in typical aircraft air distribution systems
in future work. In these configurations, the air conditioning
ductwork is commonly composed by short flattened
accessories with non-conventional cross
coefficients are not available in t
