Natural ventilation in a room, transition from natural to adverse forced convection

Résumé

This study presents 2D numerical simulations of natural ventilation in a room equipped with two openings, one low and one high. The main features are commented in terms of flow and heat transfer. We first focus on pure natural convection within the framework of the ADNBati benchmark, and validate the numerical model this way. Then we study the transition to adverse forced convection (the flow is eventually reversed) and highlight the main changes due to transition. Lastly, we present a method for coupling CFD simulations with a multizone model.
