Do increased flow rates in displacement ventilation always lead to better results?

ABSTRACT

Indoor ventilation is essential for a healthy and comfortable living environment. A key issue is to discharge anthropogenic air contamination such as CO\(_2\) gas or, of potentially more direct consequence, airborne respiratory droplets. Here, by employing direct numerical simulations, we study mechanical displacement ventilation with a wide range of ventilation rates \(Q\) from 0.01 to 0.1 m\(
