Краткое описание

Numerical investigations are carried out to study the behavior of near wake flow for flow past a transversally vibrating square cylinder using developed computational code. Two-dimensional computational study is conducted over a range of frequencies of cylinder vibration. The nature of vortex shedding is found to be contingent of the frequency of excitation of the cylinder and observed to vary characteristically. The temporal evolution of the unsteady wake is presented. The unsteady forces on the vibrating square cylinder are computed and are compared with those on a stationary square cylinder. Further results include dependence of vorticity fields as well as of wake Strouhal number on frequency of excitation of the vibrating cylinder. In addition, a comparison between drag forces for flow past transversely vibrating square and circular cylinders for similar amplitude and frequency of cylinder vibration has been presented as a validation of the tested computational code.
