TR-PPIV SYSTEM FOR UNSTEADY VOLUMETRIC FLOW MEASUREMENTS
Abstract
A system consisting of a Time-Resolved Plenoptic Particle Image Velocimetry (TR-PPIV) is requested. The system will greatly improve the quality of the PIÕs experimental research facilities and will enhance his capabilities to conduct fundamental studies of 3-D models undergoing static and dynamic motions. The results obtained using the requested system, with the PIÕs existing Time Resolved Particle Image Velocimetry system, will significantly enhance his capability to reveal physical mechanisms dominating three-dimensional, unsteady flows. The system will be used for an ARO-funded project to control reverse flow over helicopter blades under static and dynamic pitch conditions, as well as other DoD-funded projects. Moreover, the requested system will enhance collaborations with other faculty members at RPI and other universities in the USA. PPIV has been demonstrated in the past as a viable single camera technique for 3D flow measurements. Compared to established four-camera tomographic-PIV and 3D-PTV, PPIV has the advantages of lower cost, a simpler setup with a smaller footprint, a deeper depth-of-field for a given aperture and potential for access to otherwise optically restricted facilities. Moreover, recent developments of a Modular Plenoptic Adaptor (MPA) enables TR-PPIV. The MPA consists of a regular imaging lens, a microlens array, a tilt-adjustable microlens mount and an optical relay, which are collectively installed onto a high-speed camera through a standard lens mount. Each component within the system is swappable to optimize for specific imaging applications. The system will be located in the Center for Flow Physics and Control (CeFPaC) at Rensselaer Polytechnic Institute. The requested system will interface with any of the existing wind and water tunnels at CeFPaC and will enhance the capabilities to conduct time-resolved volumetric flow measurements during static and dynamic conditions. Moreover, the system can be used by other members of CeFPaC at RPI for other DoD- and industry-funded projects, which will enhance the research-related education.
