China Solar Collector Project Photothermal Equipment
Optimizing photothermal conversion efficiency in a parabolic trough direct absorption solar collector For instance, Ehsan et al. investigated the photothermal efficiency of a ferrofluid-seeded solar collector under non-uniform magnetic fields and found that 0.8 vol% Mn-Zn Fe 2 O 4 /water ferrofluid increased the collector efficiency up to 52.15 % with a
