The Unversity of Ottawa is pleased to invite qualified proponents to submit a proposal for Tomographic (Particle Image Velocimetry (PIV) and Laser Induced Florescence (LIF) Systems to be housed in the Hydrolics Laboratory of the Civil Engineering Department in STEM building.
The University’s budget for the system, including warranty, installation and training, is $1,225,000.00 CAD before tax. The budget is provided as a reference, the University reserves the right to award a contract at a lower or higher value at its sole discretion.
Scope of the Project:
The Tomographic PIV-LIF System will be used to measure the velocity, concentration and pressure fields in a flume containing different types of currents and jets. The required measurement capabilities are further described below (Application 1: Large Flume, Application 2: Bend Flume). The PIV system should be able to collect data in different commonly used settings, such as 2D2C, 2D3C, and 3D3C, with a particular emphasis on tomographic flow measurements and calculation of the tomographic pressure field from PIV and PTV data, as well as 2D measurement of the concentration field preferably synchronized with PIV.
General Description of Instrument, System and Service:
The instrument is a tomographic particle image velocimetry (Tomo PIV) as well as a particle tracking velocimetry (4D PTV) system coupled with a stand-alone laser-induced fluorescence (LIF) for fast and slow flows and scalar concentrations, as described in Application 1: Large Flume, and Application 2: Bend Flume. The system is equipped with serveral components including, but not limited to: a high-performance laser and LED, a synchronizer/timing unit and high-performance computer for PIV, a suitable computer for LIF, a second synchronizer and a laser energy monitor for LIF, all required accessories such as camera mounts, comprehensive independent software for PIV and LIF, with a tomographic pressure measurement module from PIV and PTV data, GPU computation module for most applications, 5 cameras, camera lenses and filters; 4 for PIV and 1 for LIF as well as software and synchronizer/timing unit for LIF, laser light guide arm, all required optical units, calibration targets , 2D Background Oriented Schlieren (BOS) software and plates, optional 3D BOS and optional ethernet compatibility. The ideal system can have a third synchronizer to synchronize all 5 cameras, LED, and laser, although not mandatory.
