Slender high rise structures are exposed to aerodynamic problems connected to the windstructure interaction, for example vortex shedding or dynamic instability (e.g. galloping). Generally the design of these structures requires the aid of wind tunnel tests on scaled models. The paper investigates the aerodynamic behavior of a bluff body and the shape is adopted for section of the tower of a cab...

Vortex shedding from cylinders has been extensively studied due to its occurrence in many engineering fields. Many experimental studies reported in the literature focus on the aerodynamics of the vortex shedding process but the literature about the radiated noise is more scarce. The aim of the work presented here is to extend the available noise data. Aero-acoustic wind tunnel tests were carrie...

The flow of fluid past a cylinder has been widely studied both analytically and numerically, and provides insight to the behavior of flow given different fluid properties. Particularly interesting is the transition from steady flow to vortex shedding in the wake of the cylinder. This behavior is dependent on several parameters, but most importantly, the Reynolds number (Re), which is a dimensio...

Shedding of vortices is a common phenomenon in the atmosphere over a wide range of spatial and temporal scales. However, it is unclear how these vortices of varying scales affect the flight performance of flying animals. In order to examine these interactions, we trained seven hawkmoths (Manduca sexta) (wingspan ~9 cm) to fly and feed in a wind tunnel under steady flow (controls) and in the von...

A finite element model of the Navier-Stokes equations is used for numerical simulation of flow past two normal flat plates arranged side by side at Reynolds number 80 and 160. The results from this simulation indicate that when the gap between the plates is twice the width of a single plate, the individual wakes of the plates behave independently, with the antiphase vortex shedding being domina...
