This is a Computational Fluid Dynamics model of a sugar beet clamp. This second version of the model will build on v1. Version 1.0 focused primarily on airflow and temperature. Version 2.0 will be expanded to include more of the thermal dynamics of the system, and to begin to bring the moisture (hydro-?) dynamics.
