Abstract

Ventilation in enclosures with a horizontal partition P. Prinos, V. Kartsoni, K. Bitoulis Hydraulics Laboratory, Department of Civil Engineering, Aristotle University Thessaloniki, 54006 Thessaloniki, Greece 1 Introduction Natural ventilation of buildings has received a lot of attention in recent years due to indoor air quality problems arising from mechanical ventilation systems. The latter have considerable cost for installation and maintainance and there have been cases where the system has failed to provide clean air resulting in the so-sailed "sick building " syndrome. Natural ventilation may be produced through the flow exchange between the interior and exterior environment due to naturally occuring pressure difference. This pressure difference may be produced by the action of the wind or by a temperature difference between the internal and external air. This type of ventilation can be divided in two categories, the "mixing ventilation" and the "displacem
