WP3 - Ventilation, development of ventilation concepts, air sanitization, CFD.

The main focus of WP3 will be on detailed and rigorous analyses of potential ventilation and air cleaning concepts to limit airborne transmission of infectious diseases. In all three subprojects in WP3, input from the numerical and experimental work in WP2 will be incorporated

WPs 3.1 and 3.2 will focus on the detailed assessment of different advanced ventilation and air cleaning concepts with the aim to reduce long-range and short-range transmission as much as possible without jeopardizing – among other things – thermal comfort and efficient energy use. WP3.1 will focus on the room level, while WP3.2 will focus on local concepts, with connections to WP3.1. Experiments and validated numerical simulations using computational fluid dynamics (CFD) are used in both subprojects. 
WP3.3 will focus on the inclusion of time-dependent ventilation scenarios from the point of view of the sources (infectious people) and receptors (healthy people) in ventilation and transmission research, which is often not or not fully included in the current state-of-the-art in airborne transmission modelling. This subproject relies on numerical simulations using the Lagrangian approach. 

WP3 will provide input to WP4 (Use Cases), to make a translation to practice, and (partly through WP4) to WP5 (Strategies for Infection Control) to come to strategies and guidelines for the prevention of airborne transmission of respiratory diseases.
