... theory of aerodynamic sound. Particle image velocimetry was employed to resolve the phase-averaged flow field characteristics around the cylinders at various phases in an acoustic wave cycle. It was found that the vortex shedding patterns of the two resonant conditions exhibit substantial differences...

... of a single cylinder. The unsteady flow field is simulated using a finite-volume method. This simulation is then coupled with a finite-element simulation of the resonant sound field, by means of Howe’s theory of aerodynamics sound, to reveal the details of flow-sound interaction mechanisms, including...

... mm (Cases A–E). The tests have been performed twice for each liquid depth. As the displacement of the roof is completely restraint, the aerodynamic wind-structure interaction effect is not included in the measured pressure. For more details of wind tunnel test, see Ref. 9 . Test conditions...

... flow is limited, and experimental testing can be cost prohibitive. The capability of using computational fluid dynamics is a test to determine its viability for determining performance coefficients. The flow field, resultant force, and aerodynamic torque on a symmetric disk butterfly valve are studied...
