Hi,

Any member knows about the model used for the analysis of the fluid behavior and heat / mass transfer characteristics when water is sprayed inside a pipe with flowing Ammonia, using CFD.

 

[Rob]

Yes. 

However, it's not simple and you need to define the modelling goals before starting to work on the project: the goals will determine the most suitable models. 

[naveedullah]

The main Goals are optimization of the mass flux and heat transfer coefficient, in the ammonia-water absorption process.

 

[Rob]

OK, and as the water is being sprayed can you use DPM? Review the model approach in the User's and Theory Guides. 

[naveedullah]

Thank you Rob, for the hint. I was also of the same opinion based on some literature study. But can we use two models for the complete analysis, DPM for sprayed water through nozzle and Eulerian for Ammonia in the pipe??

I mean, DPM for Injection  and Eulerian for Absorption. 

[Rob]

Euler in the above context is a multiphase model - as opposed to Euler flow which is the physics name for the continuous flow.
