The appropriate heat-carrier was studied: distilled water, nanowires on the basis of TiO2 and aluminosilicates - under conditions of free and forced convection (the Re criterion varied in the range from 800-3000). The cooling of the heaters (Nihrom 0.3 mm in diameter) was investigated at water film boiling with the addition of nanofluid at a temperature not less than 95 ° C. It was recorded a drop in the temperature of the heaters under different modes of movement of heat-carrier. At the computerized installation, it was studied and proved the possibility of emergency cooing of the overheated heat exchange surface with the help of nanofluid in the event of a boiling crisis and a steady increase in thermal load.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
