Screened Expanding Turning Vane Concept

The paper presents the screened expanding corner vane concept, which can turn a channel flow by 90 degrees, while simultaneously increasing the flow area by at least a factor of two and thus halving the mean velocity, all without incurring any significant flow separation. The concept is demonstrated...

Description
Summary:The paper presents the screened expanding corner vane concept, which can turn a channel flow by 90 degrees, while simultaneously increasing the flow area by at least a factor of two and thus halving the mean velocity, all without incurring any significant flow separation. The concept is demonstrated experimentally, and investigated with analytical and computational models. One target application is an ultra-compact closed-circuit wind tunnel, whose overall length is less than half of a conventional wind tunnel with the same test section.
