4.3. Boundary conditions

The boundary conditions were imposed by the pre-processing program Gambit and completed with functions and values in the Fluent CFD simulation program [12]. The boundary conditions also took into account the conditions inside the climatic chamber (tenv = 25C, Φenv = 60%, vair = 0.2 m/s, according to EN-ISO 23953); as there are different boundary conditions for the horizontal grill (GPA) and base grill (GRA), these are presented separately.
