Simscale vortex shedding frequency
Webb24 mars 2024 · High-frequency vortex shedding is observed in the wake of the prism for the ranges with a galloping-type response, suggesting that the structure’s oscillations are at a lower frequency compared with the shedding frequency and its amplitude is larger than the typical VIV-type amplitudes, when galloping-type response is observed. JFM … Webb22 dec. 2024 · The frequency of vortex shedding f shin the wake depends on the frequency of the perturbation fw. More precisely, there is a fundamental synchronization region in which f shis controlled by the imposed perturbation, which is referred to as the vortex shedding lock-in regime [5,6].
