Experimental Study on Solar Nanofluids
A. Gimeno-Furió, M. H. Buschmann
Abstract:
Experiments to prove whether or not black nanofluids with different stabilisations and ordinary Chinese ink are suitable to be employed as solar nanofluids in volumetric solar absorbers are carried out. For that purpose a test rig consisting of an artificial sun and a sample holder for different black liquids is built and employed for radiation experiments. It is found, that chemical stabilisation and concentration have a significant influence of the practicability of solar nanofluids. Moreover, measured absorption spectra indicate a change caused by heating during the experiments.
Keywords:
