Abstracts:
Results of an experimental investigation process evaporation of water drops with carbon nano- tubes are submitted. Drops of pure water and nanoliquid evaporated in a stream of dry air in a range of temperatures To = ~ (20 ÷ 200)0 C and velocities Vo ~ 2 ÷ 5 m/s. Initial diameter of drops was equal do = 2 ÷ 3 mm, thus Reynolds number made Re = 500 ÷ 2000. In experiments were used carbon nano- tubes in length less than 1 microns, and diameter 1.3 nanometers. The initial mass contents of carbon particles in a drop was constant, and it made ~ 0,1 %. Experimental researches of flow rate drops evaporation and the temperatures of its surface which has been carried out with the help of an infra-red microscope have shown, that addition carbon nano- tubes in base a liquid (water) practically does not affect laws heat and mass transfer. |
