1997 Experimental Study of a Spray Flash Desalination
In this paper, an experimental study of spray flash evaporation is carried out for the OTEC plant using an integrated hybrid OTEC cycle and desalination. Superheated water at temperatures of 24°C, 30°C and 40°C are injected into a low pressure chamber through cylindrical nozzles.
The nozzles used are made of stainless tubing with internal diameters of 10, 15 and 20 mm and a length of 81.3mm. The temperature of the superheated water in the flash chamber is measured by 26 thermistors. The mean velocity of the superheated water varies from 0.89 to 4.46 m/s. An empirical equation for predicting the non-equilibrium temperature difference is obtained. By using this equation, designers will be able to easily obtain the non-equilibrium temperature difference and the rate of fresh water production.
