Spray flash evaporation
WebSpray flash evaporation is an ultrafast evaporation phenomenon that happens when the superheated liquid is sprayed into a low-pressure environment, which has gained more attention due to the great potential in the enhancement of evaporation capacity. In the isolated evaporation of spray flash, the latent heat is self-supplied by droplets ...
