Nanofluids are colloidal dispersions of nanoparticles of various nature and chemical composition in traditional heat carriers. Today it is a promising heat carrier for the needs of the nuclear industry, energy, metallurgy, electronics, laser emitters, and power transformers.
The average particle size, nm 70-3000. Particle concentration, wt. % 0.5 – 1.0. Sedimentation stability 1.5 – 2.0 months. The critical flux is q · 10–6, W / m2 3.5–3.8. Heat transfer coef-ficient, α, W/m2. K 35000 – 52000.
Nanofluids are able to increase the critical heat flow by 3-4 times compared to distilled water, in contrast to single-phase coolants to avoid a sudden onset of the boiling crisis. They have high colloidal resistance and resistance to multiple boiling cycles – cooling, low cost, affordable and environmentally friendly.
