説明
To clarify the effect of the aspect ratio on the pulsating flow through the rectangular channel the pulsating flow with a reciprocated 50Hz fluctuation has been investigated experimentally. The experiment was carried out with two different aspect ratios (α??1, 8.33) and the technique of PIV with the recursive direct cross-correlation was used to accomplish velocity field measurements. The PIV measurement was synchronized with the AC power supply to the pulse pump and the phase averaged velocity profiles were measured at 10°phase angle intervals. The experimental results revealed that the ensemble averaged axial velocity profile changes from the parabolic profile to the flat one according to increase of the aspect ratio from 1 to 8.33. It was found that the phase averaged axial velocity profile changes with the phase angle and the inflection points due to the friction of the channel wall appear near the wall in those profiles.
