Species Transport Models

This area of research explores species transport using complex multi-physics models to understand spatial and temporal distribution on smaller and larger scales of nutrients. IIHR researchers currently use the OpenFOAM (free platform) and FLUENT models, both of which have been extended through in-house codes developed to improve mass transport.

Present research covers the use of OpenFOAM to define our own solvers to encapsulate important physical, chemical, and biological processes for nutrient removal.
