  Spray nozzles are used in many applications such as cleaning, cutting, and spraying. Spray nozzles come in many varieties, and are usually classified according to the specific mode of atomization they employ. In this chapter, twin fluid, swirl, hydraulic, ultrasonic, rotary, and electrostatic nozzles are discussed. 3. DRIFT [1], [2] models the dispersion of two-phase clouds, but it does not include a model for liquid rainout2. For flashing instantaneous releases, the source term model ACE [3] includes an estimate of liquid rainout at the source correlated with superheat and based on observations from experiments of flashing instantaneous releases.

The aim of the project is to increase the understanding of the behaviour of sub-cooled non-flashing and superheated flashing liquid jets, and to improve the prediction of initial droplet size, droplet dispersion and III of the JIP first included scaled experiments for materials with a range of volatilities (water, cyclohexane. Atmospheric Dispersion Model Spillage of Cryogenic Liquid into a Diked Area Choice of Example - Release Rate a Function of Time Input to SLAB Input to DEGADIS Spillages onto Water Additional Considerations Heat Sources Spreading Pool Advanced.

  - Secondly dispersion calculations are carried out to determine the concentrations of the hazardous chemical when the cloud travels in the downwind direction. This includes effects of jet, heavy-gas and passive dispersion. In the case of a two-phase release rainout may occur, and pool formation/spreading and re-evaporation is modelled. Dispersion of Two-phase Flashing Jets. Dense Gas Dispersion. Dispersion of Dense Gas: Source Terms. Dispersion of Dense Gas: Models and Modeling.
