Intensjonskunngjøring-Multi-scalar Imaging System

Om oppdraget

The Fluid Mechanics group at NTNU wishes to extend our existing flow measurement capabilities to include the ability to simultaneously measure heat-release/temperature/species (scalar) fields in reacting flows with a new dual LIF system.

We currently have a two stereoscopic PIV systems from LaVision GmbH which comprise of 2 low-speed lasers (10 Hz), 4 (25Mpx) PIV cameras and 3 (5Mpx) sCMOS cameras, frame grabbers, acquisition PCs, the timing and triggering units and the PIV acquisition and processing software. We now require integration of a high power LIF system that can measure multiple species.

We wish to purchase a dual laser induced fluorescence (LIF) system for combustion diagnostics (OH and NH PLIF)) which needs to also be integrated with existing equipment in the Thermofluids research group at NTNU. The system must provide two separate dye lasers and two pump lasers, where one of the pump lasers must be able to provide at least 50-60 millijoules of energy per pulse in the ultraviolet (for OH-PLIF) whereas the second pump laser must be able to deliver 25-30 millijoules of energy per pulse. Image intensifiers and cameras, power meters, optics, acquisition and software that is compatible with our existing systems must be included. For this reason, we need to purchase it from the same manufacturer as our existing laser systems (due to the hardware we cannot integrate LaVision equipment with their competitors’ systems, and vice versa).

Purchasing a similar system from another supplier would result in duplications of much of the hardware already in our laboratory but without the compatibility of combining the new hardware with our existing equipment to make a larger system with multiple lasers and cameras to perform simultaneous measurements. Integration with existing systems is essential to several ongoing projects funded by the EU. It is thus imperative that we purchase the new systems from the original supplier.
