New method for reducing ventilation cost through optimized air circulation in Green Houses

The numerical presented results are about the turbulent airflow over a typical pitched-roof agricultural structure. The airflow simulation is based on the solution of the Navier-Stokes equations and continuous equation with the finite element method. Taking into account the proper boundary condition...
