Strouhal numbers of inclined flat plates
WebApr 14, 2016 · Abstract In this study flow structures in the wake region downstream of two inclined flat plates in tandem arrangement have been investigated. Different gap ratios (0.5< g/D <2.0) between the... WebTwo Strouhal number plots are presented in Figure 4, the first is for velocity measurements between the plates at various gap ratios and inclination angles, whilst the second is for velocity measurements downstream of the second plate at the same configurations.
