Matched index of refraction flow facility

April 12, 2024

Matched Index of Refraction (or MIR) is a facility located at the Idaho National Laboratory built in the 1990s. The purpose of the fluid dynamics experiments in the MIR flow system at Idaho National Laboratory (INL) is to develop benchmark databases for the assessment of Computational Fluid Dynamics (CFD) solutions of the momentum equations, scalar mixing, and turbulence models for the flow ratios between coolant channels and bypass gaps in the interstitial regions of typical prismatic standard fuel element or upper reflector block geometries of typical Very High Temperature Reactors (VHTR) in the limiting case of negligible buoyancy and constant fluid properties.

Functionality edit

MIR uses Doppler Velocimetry to produce a three-dimensional image of a model inside the loop. To do this, the loop circulates about 3500 gallons of semi-transparent mineral oil similar to baby oil. Special quartz models, built to scale, are inserted into the loop near the observation equipment. MIR is capable of analyzing a variety of models, including the interior of nuclear reactor cores.

The purpose of MIR is to allow researchers to analyze a model's fluid properties; how its structure interacts with the flow of air, water or another fluid medium through and / or around it. In this way, MIR is somewhat comparable to a wind tunnel. The information MIR can provide is valuable to researchers who want to evaluate a design.

Once the oil is flowing and is held at a defined temperature, the oil takes on the same refractive index as the quartz model. This refractive index matching is a common technique using in liquid flow experiments and allows researchers and instruments to see the flow within facility without distortion at the interface between the models and oil.[1] Researchers can examine flow fields using particle image velocimetry through adding small particles to the oil or just using impurities in the oils.[2]

Current Experiments Involving MIR edit

The MIR VHTR Bypass Flow Experiment will measure flow characteristics in the coolant channels and interstitial gaps between typical prismatic block standard fuel elements or upper reflector blocks. The experiments use optical techniques, primarily particle image velocimetry (PIV) in the INL MIR flow system. The benefit of the MIR technique is that it permits optical measurements to determine flow characteristics in passages and around objects to be obtained without locating a disturbing transducer in the flow field and without distortion of the optical paths. Unheated MIR experiments are first steps when the geometry is complicated. [3]
