New Methodology for the Estimation of StreamVane Design Flow Profiles
… created by Virginia Tech, identified as the StreamVane, has the ability to produce various swirl distortion flow profiles. In its current state, the StreamVane methodology generates a design swirl distortion at the trailing edge of the device. However, in many applications the plane at which …

Investigation Into Flutter of Complex Vane Packs
… engines in different distortion patterns, the StreamVane and ScreenVane systems have been developed. A StreamVane consists of a complex vane pack that is custom designed for each distortion profile and the ScreenVane combines the StreamVane with a pressure distortion screen for testing engines …

Stereoscopic Particle Image Velocimetry Measurements of Swirl Distortion on a Full-Scale Turbofan Engine Inlet
… was generated by a novel new method, dubbed the StreamVane method, and measured in a sub scale tunnel using stereoscopic particle image velocimetry (SPIV) as a precursor for swirl distortion generation and characterization in an operating turbofan research engine. Diagnostic development efforts …

Initial Investigations into the Failure Modes of a Swirl Distortion Generator Using Computational Methods
… the development of these integrated systems. The StreamVane swirl distortion generator was developed by Virginia Tech to provide cost and time efficient ground testing methods for BLI research. StreamVanes are constructed of unique vane packs that are specifically tailored to generate a desired …

The Design and Analysis of Bluff Body Dynamic Distortion Generators
… in ground test facilities needs to be developed. StreamVanes and ScreenVanes were developed at Virginia Tech as a way to generate real-world swirl and pressure distortion profiles for engine testing. However, they are only capable of generating steady distortion patterns, which limits the scope of …

A Comprehensive Three-Dimensional Analysis of the Wake Dynamics in Complex Turning Vanes
… vanes. The vane packs were designed by the StreamVane swirl distortion generator technology, a design system that can efficiently reproduce swirl distortion for compressor rig and full turbofan engine testing. StreamVanes consist of an array of turning vanes that commonly contain variations …

Design and Low-Speed Validation of a Tailored Low-Loss Flow Straightening Device
… upon the fundamentals of the swirl-producing StreamVane design methods and is thus designated as the Inverse StreamVane. The complex arrangement of turning vanes in the StreamVane and Inverse StreamVane alike creates a spanwise variation of vane spacing. Calculated by a proximity approximation …

Fluid Dynamics of Inlet Swirl Distortions for Turbofan Engine Research
… distortion profiles were generated through the StreamVane method in a low-speed wind tunnel and in a full-scale turbofan research engine. Stereoscopic particle image velocimetry (PIV) was used to collect three-component velocity fields at discrete planes downstream of the generation of the …

Experimental Investigation of Fan Rotor Response to Inlet Swirl Distortion
… attached to the fan case; for distorted tests, a StreamVane swirl distortion generator was inserted into the inlet duct. The StreamVane was designed to induce a swirl distortion matching results of computation fluid dynamics models of a conceptual blended wing body aircraft at a plane upstream of …
