Current standards and guidelines are not enough for the required ventilation in confined space nor do they sufficiently accentuate need for ventilation nor provide guidance on how to ventilate confined spaces based upon area, volume etc. Ventilation is optimistic engineering control that can usually be...
Studies on airflow through a mine ventilation network using tracer gas have revealed that quality of air is affected by the presence of dead spaces along the mine airways. To further study the effect of dead spaces on quality of air in dead space, studies were conducted in both laboratory mo...
In the outbreak of respiratory diseases such as COVID-19, this ventilation factor is particularly important for the assessment of effective ventilation in confined spaces. Computational fluid dynamics (CFD) techniques can be used to simulate individual cases and obtain more accurate and case-specific ...

Buildings are an important source of energy consumption in developed countries. In Europe, buildings account for approximately 40% of final energy consumption. Increasing demands for thermal comfort and concerns on health and hygiene levels in confined spaces are likely to push this figure upwards. V...

The ventilation task is to regulate the air change in a confined enclosure to create the intended temperature, velocity, concentration field, etc. For mechanical ventila- tion, the air is supplied to given spaces in the form of jets by air diffusers or openings of the air passage. The ...
