Purpose of the development: Prospective coolant for the needs of laser emitters, power transformers.

Recommended application field: Nuclear industry, energy, metallurgy, electronics.

Technical characteristic: The average particle size, nm 70-3000. Concentration of particles, mass. % 0.5-1.0. Sedimentation stability, months 1,5-2,0. Critical heat flux, qх10-6 W / m2 3.5-3.8. Heat transfer coefficient, a, W / m2 K 35000-52000.

Advantages over analogues: Nanofluids are able to increase the critical heat flux by 3-4 times compared to distilled water, in contrast to single-phase heat carriers, they allow to avoid a sudden onset of a boiling crisis. They have high colloidal stability and resistance to multiple boiling-cooling cycles, low cost, affordable and environmentally friendly.

The development stage readiness: Tested experimental exploitation order
