An Alternative View on the Theory of Cross-Ventilation
International Journal of Ventilation, 2004The mechanism of cross ventilation is dealt with in this paper. The results are obtained by a combination of wind tunnel studies and CFD predictions using a Reynolds stress model as the turbulence model. All buildings have been exposed to a uniform velocity field and therefore the reference flow rate for an opening is equal to the velocity multiplied ...

Analysis of Natural Cross-Ventilation for Building Environmental Control
2010An ancient Japanese well-known essayist, named Kenko, a Buddhist priest, wrote the “Essays in Idleness,” which is called “Tsurezure-gusa” in Japanese. Section 55 of these essays says, “ A house should be built with the summer in mind. In winter it is possible to live anywhere, but a badly made house is unbearable when it gets hot.” Even in modern days,

NATURAL CROSS VENTILATION CLASSROOMS: CO2 AND PROTECTION AGAINST PANDEMICS
DYNALa ventilación natural cruzada es considerada una estrategia efectiva y sostenible frente a pandemias respiratorias en espacios confinados. La entrada de aire en un aula, a través de puertas y ventanas, mejora la calidad del aire interior (Indoor Air Quality - IAQ), disminuye la transmisión de enfermedades respiratorias con una distancia social ...

Airflow assessment in cross-ventilated buildings with operable façade elements
Building and Environment, 2011This paper presents an experimental study of basic cross-ventilation flow characteristics that are essential inputs for accurate natural ventilation modelling and design. The study focuses on a generic single-zone building model tested in a wind tunnel under isothermal flow conditions (wind-driven ventilation).

Effect of indoor buoyancy flow on wind-driven cross ventilation
Building Simulation, 2012Designing for wind-driven cross ventilation is challenging due to many factors. While studies have focused on the difficulty of predicting the total flow rate and measuring opening characteristics of cross ventilation, few have investigated the impacts on the distribution of indoor air.

Cross-Ventilating Rat Model: Pulmonary Functional Status of Participating Animals
Journal of Aerosol Medicine, 1988ABSTRACT We have developed a new experimental animal model, called the cross-ventilating rat model, for use in pharmaco- and toxicokinetic studies involving the inhalation of traceable agents. The model consists of two anesthetized rats interfaced in a manner so that the lower respiratory tract of one of the participants (Nasal Compartment Recipient ...

Large eddy simulation of cross-ventilation of an isolated building
2017In the present paper the cross-ventilation of an isolated building immersed in a neutral atmospheric boundary layer (ABL) with openings on the windward and leeward facades is investigated by means of numerical simulations at wind tunnel scale. Specifically, the large eddy simulation (LES) approach is employed, with a wall shear stress model at the ...
