Analysis of Pressure Pulsation Induced by Rotor-Stator Interaction in Nuclear Reactor Coolant Pump
Published 2017-01-01“…The study finds that, at nominal flow, the flow rate distribution in guide vanes is relatively uniform and the pressure pulsation amplitude is the smallest. Besides, the vortex shedding or backflow from the impeller blade exit has the same frequency as pressure pulsation but there are phase differences, and it has been confirmed that the absolute value of phase differences reflects the vorticity intensity.…”

Computational assessment of winglet-induced variations in pressure coefficients on NACA 4418 aircraft wings
Published 2025-01-01“…The results indicate a significant modification in the pressure coefficient distribution due to the winglet, particularly at the wing tips with NACA 4418 using the angles of attack (AoA) at 4°, 0°, 4°, 8°, 12°, 16°, 20° and 24° for velocity of 30 m/s, where the reduction in vortex strength leads to decreased induced drag. The results reveal that the pressure coefficient becomes high at 20%C, then decreases to a minimum value at 45%C and then rises gradually up to again a higher value at 80%C for the angles of attack of − 4° and 0° at three airfoil velocity. …”
