Abstract
The present paper gives an experimental coverage of the flashing process through a superheat liquid jet using tap water at low pressures. The spray nozzles of diameters <0.4 mm, and the working injection pressure is up to 6 bar, the experimental study was carried out with a degree of superheat ranging between 2 and 18 K, inlet feed temperatures from 40 to 70°C, and at different feed flow rates by measuring the inlet and outlet temperatures through the flash chamber, in vacuum. The amount of the flashed vapor can be determined by condensing it and comparing with the calculated one at different feed flow rates. The relation between the degree of superheat and the amount of the flashed vapor can be evaluated through this work. Also, through this experimental work, the flashing efficiency was measured and there was a good agreement with the one proposed by other authors.
