description This paper presents a falling film generating apparatus for testing ammonia vapor generation rate with/without nanoparticles. The comparative experiments were conducted to study the influence of the nanoparticle and surfactant with their mass fraction varying from 0% to 0.5%, the ammonia-water with the concentration varying from 25% to 40%, and the temperature of the hot water on ammonia vapor generation rate. Adding the optimal mass fraction of Zinc Ferrite(ZnFe2O4) with sodium dodecyl benzene sulfonate(SDBS) into ammonia water can significantly improve the generation rate of ammonia vapor. The effective generation ratio can be increased by 60% with the mass fraction of 0.1% ZnFe2O4 and the mass fraction of 0.05% SDBS when the concentration of the base fluid ammonia-water varies from 25% to 40%. However, only adding the dispersant SDBS will weaken the generation rate of ammonia vapor. In order to achieve optimal result, both positive and negative effects of dispersant on generation process are need to be taken into account. In view of the enhancement of ammonia-water nanofluid on generation process, the development of AARS should have a more promising future for their commercial application.
