Radiative Properties of a Nanofluid Mixture
Sinopsis
In this paper, the suitability of nanofluids as a heat transfer fluid in direct solar absorbers is analyzed. At first, a possible power plant design is proposed in which the nanofluid can be used as an absorber fluid without a secondary cycle for the power generation. Additionally it is shown that an alternative absorber design could offer advantages compared to conventional solar absorbers. Therefore, a theoretical model based on the Mie-theory is depicted and used for an a priori screening of promising nanoparticle materials for solar absorption purpose. The calculation is validated with a measurement of temperature increase over time for irradiation with a laser source.
