Notes:
The ADREA-HF code is a 3-D time dependent finite volume code for vapour cloud dispersion under development at NCSR “DEMOKRITOS” and JRC ISPRA. ADREA-HF is especially suitable for complex terrain and is also designed to treat liquid phase change in the vapour cloud (two phase releases). The fluid dynamics and thermodynamics are described by the mixture mass, momentum and internal energy equations whereas mass conservation of the heavy fluid component is fulfilled through a separate mass transport equation. The system is assumed to be in thermodynamic equilibrium, but the liquid and gas phases can have different velocitites. The present work falls within the framework of the code validation for two phase relases. The experiment selected for comparision was the DT1 Run from the Desert Tortoise ammonia spill series of experiments. The results are given in terms of ammonia concentrations as well as temperatures. The comparison with the experimental data is discussed.
