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

, 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 ...

Natural ventilation for the prevention of airborne contagion. [PDF]

, 2007
BACKGROUND: Institutional transmission of airborne infections such as tuberculosis (TB) is an important public health problem, especially in resource-limited settings where protective measures such as negative-pressure isolation rooms are difficult to ...

Natural Ventilation Properties and Thermal Environments of a Closed Underground Mine

Journal of MMIJ, 2016
In this study, we measured properties of natural ventilation in a closed Arakawa mine and considered those properties theoretically. The natural ventilation pressure was estimated from the ratio of leakage airflow to the airflow when the ventilation door

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

Epidemiology 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.
