Separation of Tasks

• It is not necessary for the process engineer to be a CFD expert (and vice versa)

• The CFD analyst creates models and uploads them to the Model Database

• The process engineer selects models from the database and uses them in process flowsheets

Summary

• APECS is enabling software being developed to couple Process Modeling and CFD for improved process design

• APECS permits process engineers to include high fidelity models in simulations of the overall plant performance – predict spatial variations in temperature, species

concentrations, phases, etc.– reduce empiricism in predicting mixing, heat transfer, etc.

Summary


– reduce empiricism in predicting mixing, heat transfer, etc.– visualize the three-dimensional distributions within your

equipment– model with greater realism, by including particle size

distributions, turbulence/chemistry interaction, multiphase flow, thermal radiation, ...

– more reliably predict off-design conditions– virtual scale-up capability based on first-principles simulation

• A variety of features are being implemented in APECS to maximize the utility and ease of use
