Numerical study of a naturally cross-ventilated building

Energy and Buildings, 2010
Abstract This paper deals with the numerical three-dimensional prediction of the induced flow patterns around and inside a building, which is cross-ventilated in a natural way. The air change rate is controlled by two opposite openings on the building envelope, as a function of wind velocity and its incidence angle. The numerical methodology is based

Cross-Gyre Ventilation of the Subtropical Gyre: An Internal Mode in the Ventilated Thermocline

Journal of Physical Oceanography, 1984
Abstract A model of cross-gyre geostrophic flow is presented. It is a two-layer model of the (Northern Hemisphere) subtropical thermocline above a resting lower ocean. The northern boundary of the gyre is taken to be a latitude circle on which the Ekman pumping vanishes.

Characteristics of Low-Profile Cross-Ventilated Freestalls

Sixth International Dairy Housing Conference Proceeding, 16-18 June 2007, (Minneapolis, Minnesota) (Electronic Only), 2007
The ventilation characteristics in a low-profile cross-ventilated freestall building were monitor in May and August 2006. Three different ventilation rates were evaluated in an 800 cow facility located in North Dakota. The high, medium and low ventilation rates selected were based on exchanging the air inside the building every 60, 120 and 240 seconds,

Cross-Ventilation of Underground Railway Tunnels

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.

The Influence of Ward Ventilation on Hospital Cross Infection

Journal of Applied Bacteriology, 1963
S ummary : A ventilation system combining fresh air intake with recirculation of ward air, through an electrostatic air filter, was introduced into a ward in which it had been shown that poor ventilation was a major factor in

Ventilation Practices in the Neonatal Intensive Care Unit: A Cross-Sectional Study

The Journal of Pediatrics, 2010
To assess current ventilation practices in newborn infants.We conducted a 2-point cross-sectional study in 173 European neonatal intensive care units, including 535 infants (mean gestational age 28 weeks and birth weight 1024 g). Patient characteristics, ventilator settings, and measurements were collected bedside from endotracheally ventilated infants.

Mechanical ventilation in amyotrophic lateral sclerosis: a cross-cultural perspective

Journal of Neurology, 1998
Mechanical ventilation is known to be an effective means of relieving symptoms of chronic hypoventilation and prolonging life in patients with amyotrophic lateral sclerosis (ALS). Various methods of mechanical ventilation are available to patients with ALS.

Windows design for maximum cross-ventilation in buildings

Advances in Building Energy Research, 2016
ABSTRACTComputational Fluid Dynamics numerical analysis is performed to investigate the ventilation performance and the internal thermal environment of naturally ventilated buildings. Several alternative scenarios are generated by varying the size of openings with different configurations of orientation and solar shading.

Development of CO2 Balance for Estimation of Ventilation Rate in Naturally Cross-Ventilated Dairy Barns

Transactions of the ASABE, 2014
Abstract. The determination of ventilation rates through naturally ventilated livestock barns is complicated and shows large uncertainties. One key issue is to develop further the measurement methods. Experiments were performed to study air exchange rates (AER) occurring in a naturally ventilated dairy barn during spring seasons.

Robotic-assisted carinal reconstruction using cross-table ventilation

Multimedia Manual of Cardio-Thoracic Surgery
Carinal reconstruction remains a technically challenging procedure for thoracic surgeons due to the complexity of airway resection and management. This is typically performed in the setting of tumour resection affecting the carina and distal trachea. Airway management of patients undergoing surgical resection of tumours involving the carina is highly ...
