Flashing Flow of LiBr Aqueous Solution in a Convergent-Divergent Nozzle (Flow characteristics in nozzle and photographic observations of droplet jet from nozzle exit)

摘要

Aiming to improve the performance of absorption refrigerators, our research group has been proposing a new type of absorber called "the mixing type absorber", which introduces an ejector in order to separate the heat and mass transfer process. In this paper, the flow characteristics of LiBr aqueous solution in a convergent-divergent nozzle have been discussed through analysis of pressure profiles, observations of droplet jet from nozzle exit and PTV measurements.
