nanofluid faasimuutuse materjali energiasalvesti
Nanofluid
The nanofluid is prepared simultaneously by adding two different reactants as seen in Fig. 4 and it gives the nanofluid long-term stability [84–87]. However, in the two-step method as seen in Fig. 5, the nanoparticles are synthesized separately either by chemical, physical, or biological methods, then mixed directly with the base fluid.
