Advanced Camera System for Measurement of Complex Flows
Abstract
The following proposal Advanced Camera System for Measurement of Complex Flows is submitted for consideration under the Defense University Research Instrumentation Program (DURIP). The instrumentation to be acquired will significantly upgrade Penn States measurement capabilities that support the research and educational goals of the faculty, staff, and students within Penn States Applied Research Laboratory (ARL), the College of Engineering, and The Graduate Program in Acoustics. As one of five DoD designated U.S. Navy University Affiliated Research Centers, ARL conducts essential research, development, and systems engineering in support of our nations priorities free from conflict of interest or competition with industry. As a core technical concentration within the Fluid Dynamics and Acoustics Office, fluid dynamics research at ARL is focused on high Reynolds number underwater applications and includes such topics as: advanced propulsor design and evaluation; cavitation and supercavitation, marine renewable energy; dynamics of gas/liquid mixtures; fully-coupled fluid-structure interaction, and biomedical fluid dynamics. These problems all involve characterizing localized, time-dependent fluid motions, the imaging of which requires high-speed acquisition and high light sensitivity.The proposed instrumentation consists of a system of six high speed scientific cameras and supporting equipment that will be used for existing and future research programs that support both student-related educational projects and research sponsored by organizations such as the Office of Naval Research (ONR), The Naval Sea Systems Command (NAVSEA), National Institutes of Health (NIH), and other government organizations. This camera system will replace four existing cameras, purchased in 2012 through a combination of an FY2012 DURIP award, sponsored research funding, and internal capital equipment funding. These existing cameras have reached end-of-life, as several have defects affecting operation and they are no longer supported by the manufacturer.In addition to replacing obsolete equipment, the proposed system will furthermore expand our measurement capability in several key areas. First, increasing the number of available cameras enables simultaneous capture of complex phenomena from more viewpoints, increasing our understanding of complex flow fields. Second, this system of six identical cameras, integrated with our existing high-repetition laser systems and software will enable increased accuracy cutting-edge tomographic Particle Image Velocimetry (PIV) or Particle Tracking Velocimetry (PTV) measurements to support full three-dimensional volumetric fluid measurements. Third, camera sensor technology has progressed in the last eight years since our previous cameras were purchased, and the specific camera selected for this proposal packages a high-sensitivity, 10,000+ frames-per-second sensor into a compact body one-half to one-quarter the size of our existing cameras, enabling installation within compact underwater housings and in other confined spaces too small for existing cameras.
