An Alternative View on the Theory of Cross-Ventilation [PDF]

International Journal of Ventilation, 2004
The 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 ...

Cross-ventilation of a room in a courtyard building

Energy and Buildings, 2016
Abstract The influence of courtyard height on the cross-ventilation of a room abating a courtyard building is addressed in this work. While the cross-ventilation performance of isolated buildings has been thoroughly documented in the literature, the phenomenon is still not tackled in the context of a courtyard building, both in isolated as well as ...

Cross-Ventilation of Underground Railway Tunnels [PDF]

Journal of Fluids Engineering, 1979
The aerodynamic merits and demerits of cross-ventilating adjacent tunnels in underground rapid transit systems are discussed. Three types of cross-ventilation are considered, namely (a) numerous small holes in the dividing wall between the tracks in a cut-and-cover tunnel, (b) a curtailed dividing wall and (c) passages linking separately bored tunnels.

Wind-driven cross ventilation with internal obstacles

Energy and Buildings, 2013
Abstract Most ventilation models do not consider the influences of furniture and obstacles on building ventilation. This study developed a resistance model to calculate the ventilation rate of wind-driven cross ventilation in a low-rise building with vertical plates in the building.

Wind-driven cross ventilation in long buildings

Building and Environment, 2014
Abstract The rule of thumb for effective wind-driven cross ventilation suggests that the building length L should be less than five times of ceiling height H . This study uses a Large Eddy Simulation model and wind tunnel experiments to investigate the mechanism behind this rule of thumb.

Novel personalized chair-ventilation design integrated with displacement ventilation for cross-contamination mitigation in classrooms [PDF]

Building and Environment, 2022
This work investigates the performance of a novel chair-ventilation design integrating ductless personalized ventilation (PV) and personalized exhaust (PE) in a classroom conditioned by displacement ventilation (DV). The aim is to protect seated students
