EFFECT OF DETACHED RIBS ON TURBULENT FLOW STRUCTURE IN A RECTANGULAR DUCT WITH
ADVERSE PRESSURE GRADIENT

rib-to-duct
height ratio,
and
pitch-to-rib height ratio,
The
experimental results of flow behaviour in the duct with and without ribs were
obtained. These results were compared to the numerical results using the
Re-Normalization group k-e turbulent model (RNG k-e). Reasonable agreement was
found between the simulations and experimental data. The flow simulation was
able to capture the major features of the flow with larger regions of
circulating flow behind the ribs.
