DOE MURI HOT Fluids Project: Spectrometry of Variable-Thickness Participating Media Megan McHugh Dr. Cho Lik Chan and David Leister 24th Annual Arizona Space Grant Consortium Symposium UA/NASA Space Grant April 17-18, 2015

Introduction Department of Energy (DOE) Multidisciplinary Undergraduate Research Initiative (MURI) High Operating Temperature (HOT) fluids division project Development of concentrating solar power applications High-temperature heat transfer fluids Goal: Design a method to obtain unique radiation signatures for participating media. Participating media was various semi-transparent liquids

Introduction, cont. Experiment: Transmission was measured across wavelengths ranging from 400 to 1000 nm and at twelve thicknesses ranging from 0 to 50 mm to find the spectral attenuation coefficients. 0, 1, 2, 3, 4, 5, 10, 15, 20, 30, 40, and 50 mm 𝐼 𝑥 =𝐼 0 ∗exp⁡[−𝛽*x] I is radiation intensity Β is the spectral attenuation coefficient

Background Scattering Mechanisms: absorption, transmission, reflection Ways to change direction: diffraction, reflection, refraction The sum of absorption and scattering is known as the attenuation coefficient 𝛽 𝜆 = 𝜅 𝜆 + 𝜎 𝑠,𝜆 β is the attenuation coefficient κ is the absorption coefficient σs is the scattering coefficient Dependent on wavelength and the properties of the radiation along the medium Have units of reciprocal length After: * ways to change direction There are three processes resulting of the interception of radiative energy and any object: absorption, transmission or reflection. So, of the photons traveling through the medium there are three different mechanisms of which they can change their direction either: diffraction which is when there’s changing in the path of a photon without collision, reflection which is when colliding with a particle a photon can be reflected from it, and refraction which is where there’s changing of direction due to a change in the medium. After: * σs is the scattering coefficient Defined as the change of direction of the radiation along a medium. After: * Dependent on wavelength and the properties of the medium Such as temperature, pressure, and the composition of the material After: * Have units of reciprocal length Because physically they represent the penetration of the wave through the medium and they are called linear or volumetric coefficients.

Background, cont. Beer’s Law: the behavior of these properties along a path, S 𝐼 𝜆 (𝑆) 𝐼 𝜆 (0) = 𝑒 −𝛽𝑆 Iλ(0) is the incident intensity on a path S (with length units) for a given direction of a medium Iλ(S) is the intensity at a location S for the same direction β is the attenuation coefficient described above

Future Directions Perform the same procedure with leaves for remote mapping. The radiation coming through tree tops can have the parts below the roots reconstructed. Dr. Ganapol has developed transport theory to perform this remote sensing. Attenuation data is necessary to make the predictions. Characterize high-temperature fluids for concentrating solar power applications.
