Résumé

The objectives of this paper were to visualize the bubble behaviour in NH3/H2O absorption and to study the effect of nanoparticles and surfactants on the absorption characteristics. Binary nanofluid which means binary mixture with nano sized particles is tested to apply nanofluid to the absorption system. Cu, CuO and Al2O3 nanoparticles are added to make the binary nanofluids into NH3/H2O solution, and 2-ethyl-1-hexanol, n-octanol and 2-octanol are used as the surfactants. The concentration of ammonia in the basefluid, that of nanoparticles in the nanofluid, and that of surfactants in the nanofluid are considered as the key parameters. The results show that the addition of surfactants and nanoparticles improves the absorption performance up to 5.32 times. It can be concluded that the addition of surfactants and the application of binary nanofluid enhance significantly the absorption performance during the ammonia bubble absorption process.
