66 -- PARTICLE IMAGING VELOCIMETRY SYSTEM SOL N68936-95-R-0255 POC Maggie Green, Contract Specialist, (619) 939-4274 or Patricia West, Contracting Officer, (619) 939-4276. The Naval Air Warfare Center Weapons Division, China Lake intends to procure a Particle Imaging Velocimetry (PIV) System. The system must consist of a complete turn-key unit for performing PIV in water tunnel, wind tunnel and free jet combusting and non-combusting flows using both photographic and charge coupled device (CCD) imaging. It must be capable of measuring 2D velocity vector fields for velocities from 1cm/sec up to 600 m/sec over flow planes of 16'' x 16'' down to 2'' x 2''. The system must be based on a dual cavity Nd-YAG laser of at least 350mJ per pulse per cavity at 30 Hz repetition rate (per cavity) allowing any time separation between the two cavity pulses. The system must be capable of handling reversing flow without directional ambiguity. Directional ambigugty removal technique must be able to handle flow rates up to 300 m/sec. System electronic imager(s) must have at least 2000 x 2000 pixel resolution at up to 2 frames per second and come complete with lenses. The analysis system must be capable of reducing PIV image data at the rate of at least 30 vectors per second. Software must have the following features: selectable pixel resolution, user configurable PIV analysis grid size, auto and cross correlation capability, automatic vector validation and interpolation, output of velocity vector field plots and ASCII data files, output of derived plots including average speed, spatial derivatives and vector plots of vorticity and strain rates. The contract will include updates to system software for a period of one year. The system must include mechanical traverse which allows positioning of the laser sheet plane (as well as the camera imaging plane) over a minimum range of 300 mm x 300 mm x 600 mm in x, y, and z axis. System manuals and training for three people shall be provided. Requests for the solicitation shall be in writing and may be sent by facsimile to (619) 927-3488 Attn: M. Green. The request should include the firm's Tax Identification Number (TIN) and Commercial and Government Entity (CAGE) Code if one has been assigned. Telephone requests will not be honored if not followed up in writing. All responsible sources may submit a proposal which shall be considered by the agency. (0107)
