Title

Performance Evaluation Of Divided Intake Ducts: Effect Of Area Ratio And Inlet Reynolds Number

Abstract

Investigations carried out on divided intake ducts with 22.5°/22.5° angle-of-turn to establish the effect of Reynolds number (Re = 6.27 · 104 to 1.88 · 105) and area ratios (2.0 to 4.0) using Computational Fluid Dynamics (CFD) code are reported. The core flow remains close to the convex wall at the duct outlet with magnitudes lower in the central region of the cross-section. It is found that static pressure recovery is around 65% and is independent of inlet Reynolds number for area ratio 2 duct (AR = 2). With increase in area ratio the static pressure recovery increases to 74% for AR = 2.5, 78% for AR = 3 and 80 % for AR = 4. The cross-velocity magnitudes at the exit for all the cases are found to be less than 5 % of the mean flow.
