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.
CFD MODEL VERSION COMPARISON
|Solver/s||PISO, with separate solvers for momentum and temperature|
|Physical model||2D. Entire domain: 39m x 13m (W x H), with clamp region of 9 x 3 in middle. Symmetrical on x-axis.|
|Mesh||6123 cells. Built with blockMesh utility|
|Boundary conditions||Ground = non-slip, Top = symmetry plane|
|Inlet conditions||U = Ux = uniform. T = T_air from weather station.|
|Note on inlet||The inlet and outlet were able to swap|
|Key fluid dynamics considerations||Porous medium: Darcy-Forchheimer parametisation||Porous medium: Darcy-Forchheimer parametisation|
|Key heat transfer considerations||T_air = f(convection, conduction, transfer between roots and air)|
T_beet = f(conduction, transfer between roots and air, heat of respiration)
CFD MODEL V2 DESCRIPTION OF PROGRESS
650 is the project code
650.01 is the version of the project (ie v2)
650.01.01 is the initial development of the model, migrating from OF9 to OF11.
