Experimental investigation on some key variables during pool water flash evaporation.

An experimental study has been performed to investigate pool water flash evaporation in a rectangle chamber. The water level was at 40 mm, 60 mm, 100 mm, and 150 mm. Initial conditions of the liquid varied from 36 to 88° C temperature and 2.1 to 48° C superheat. The experimental results showed that the initial water temperature, the superheat and the water level are significant to the water temperature transients in flashing process and the value of NEF when flash evaporation calm down. Experimental study allows us to correlate the evolution of water temperature. [ABSTRACT FROM AUTHOR]
