• The zone of interest in 2D3C PIV is a plane (vertical or horizontal) over the entire width in which the distance of the farthest point from the glass wall is 1.5m. For the tomographic PIV, the distance of the zone of interest from the glass wall is 0.9m.

Application 2: Bend flume

• Speed 1 m/s
• Volume 0.3 m long x 0.1m wide x 0.65 m deep Frequency: 100 and 200 Hz
• The zone of interest in 2D3C PIV is a plane (vertical or horizontal) over the entire width in which the distance of the farthest point from the plexiglass wall is 1.0m. For the tomographic PIV, the distance of the zone of interest from the plexiglass wall is 0.65.

 
1.2 - TomoPIV: The system must be able to perform 2D2C, 2D3C, and tomographic PIV measurements. All required components, including a workstation, synchronizer, as well as all accessories, including mounts, must be provided.
The system must have at least four cameras, The cameras must be at least 3MP @ 1kHz with at least 36GB RAM. The system must be able to perform volume self-calibration for TomoPIV applications.
1.3 - LIF: The system must include a stand-alone planar LIF product, including a camera, (the same as those of PIV - at least 3MP @ 1kHz with at least 36GB RAM), independent software from that of PIV (both PIV and LIF can work, simultaneous and independently but not necessarily altogether syncronized), suitable computer, synchronizer/timing unit (separate from that of PIV) with the required accessories, including a mount. The Camera and PC of LIF system must be able work with the laser @1kHz (refer to Mandatory Requirement 1.8). The system must have a laser energy monitor and be able to apply the advanced operations of laser energy correction as well as laser absorption correction. All required software and hardware must be provided.
1.4 - PTV: The system must be able to perform 4D  PTV for time-resolved computation of 3D volumetric flow field
1.5 - BOS: The system must be able to use Background Oriented Schlieren (BOS) method to measure 2D density field of thermal flows as well as 2D-2C displacement field.
1.6 - Pressure: The system must provide tomographic pressure field from TomoPIV and 4D PTV.
1.7 - GPU: The PIV software must have GPU capacity at least for 2D3C case.
1.8 - Laser: The system must include a laser system with a minimum energy of at least 2 x 25 mJ/pulse (@527 nm) at 1 kHz.
1.9 - LED: The system must illuminate an area of at least 300 cm­­2 using an LED component with energy of at least 25 mJ/pulse  @1400Hz
1.10 - The system must have a minimum of five (5) lenses of 50mm, five (5) filters, and five (5) Scheimpflug Camera Lens Adapters

2.0 - Product History
2.1 - Proponent must have previously sold a minimum of 10 units of a comparable system and must provide contact information for five (5) references who have acquired a comparable systems. Refer to Appendix E – Reference Consent Form.

3.0 - Installation, Training and Warranty
3.1 - Installation must be included 
3.2 - Proponent must provide on-site training of a minimum duration of 8 days. Training must be conducted by an expert, covering all modules/submodules (including tomographic training modules), components and software of the proposed system, as well as conducting the measurements in sample experiments for Applications 1 and 2 (Large Flume & Bend Flume) stated above (refer to RFP Section 1.2 – Statement of Requirements).   
3.3 - Must include one (1) year warranty on parts and labour.  

4.0 - Other Requirements
4.1All electrical components must have CSA (Canadian Standards Association) certification, or accepted equivalent as per Electrical Safety Authority Recognized Certification Mark at the following link: https://esasafe.com/electrical-products/recognized-certification-marks/
Otherwise, all electrical components must be able to undergo the appliable electrical inspection, and/or, certification, without voiding the system warranty.
