Modeling of uncertainties from spanwise asymmetries in upstream conditions and measurement plane location for flow past a circular cylinder confined within a duct
This study numerically investigates two sources of uncertainties that may influence measurements of flow past a circular cylinder confined in a duct. These being spanwise asymmetries in upstream profiles and measurement plane location. We find variations in upstream profiles strongly affects wake topology. Whereas, due to end effects, uncertainties in measurement plane location strongly influences measurement of flow statistics. Hence, a combination of both may yield uncertainties in flow measurements. These insights may be used to guide experimental investigation of moderate to highly confined flows.
