Description
In upward spray flash desalination system, the experiment is carried out to clarify the influence of jet flow and jetdistribution pattern.<BR>An superheated water at temperature of 24.0, 30.0, 35.0, and 40.0°C is injected upward into a depressurized chamber through a cylindrical nozzle with the internal diameter of 83.1mm.The range of the mean velocity of the superheated water is from1.2 to 3.6m/s. The horizontal temperature distribution of the upward jet is measured by 10 thermo resistances, which are movable along the jet axis, at 26 locations between 0.0mm and 700.0mm from the nozzle exit.<BR>The results show that the upward jet flash evaporation is classified into 4 patterns called liquid film, cyclic, droplet, and spray evaporation. By the dimensionless arrangement, the horizontal temperature distributions of the upward jet are categorized into 2 types. The approximate equations are proposed to estimate the area of influence from the flash evaporation by a nozzle.
