Large-eddy simulations to define building-specific similarity relationships for natural ventilation flow rates

open access: yesFlow, 2023
Natural ventilation can play an important role towards preventing the spread of airborne infections in indoor environments. However, quantifying natural ventilation flow rates is a challenging task due to significant variability in the boundary ...

The natural ventilation of unheated ‘closed rooms’ [PDF]

open access: yesEpidemiology and Infection, 1946
The experimental method for, and analysis of, more than 300 determinations of air influx rates into two unheated ‘closed rooms’ of opposite aspects each fitted (a) with wall grating, or (b) with flue, are described. The average relative efficacy for all observed wind velocities of (a) of 50 sq.in.

Quantifying the performance of a top-down natural ventilation Windcatcher™ [PDF]

open access: yes, 2009
Estimating the performance of a natural ventilation system is very important if one is to correctly size the system for a particular application. Estimating the performance of a Windcatcher™ is complicated by the complex flow patterns that occur during ...
