SprayInjectorVLE L3 advanced

Created Wednesday 12 June 2013

A spray injector model featuring the dynamic cooling of steam by a valve-operated injection of water.

1. Purpose of Model



This model is recommended for all situations where a spray injector is needed and detailed information on the behaviour of the two phases in the outlet zone is needed.
