Unsteady Multi-hole Probe Measurements of the Near Wake of a Circular Cylinder at Sub-critical Reynolds Numbers

Unsteady multi-hole probe measurements are conducted to investigate the near wake of a circular cylinder at Reynolds numbers which vary between 3000 and 10000. Besides the pressure measurements, data with a triple-wire probe are recorded to validate the multi-hole probe results. The streamwise and lateral velocity components and their higher order statistical moments are investigated. Furthermore, frequency spectra of the velocity components are shown. Experimental results of the unsteady multi-hole probe demonstrate a good match with the hot-wire results as well as numerical and experimental data from the literature.      «
