LoginThe evaluation of a code can be done by investigating two items: solving the correct equations and solving equations correctly and eficiently. An indoor airflow code VentAirI has been developed and is evaluated here.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
The concentrations of indoor pollutants should be maintained below recommended values at all occupied locations at any time.
A mathematical model has been developed which will facilitate the prediction of infiltration rates within multi-zone buildings.
The airflow pattern and thermal comfort in a naturally ventilated classroom were predicted using CFD techniques.
Results of 3-D computational fluid dynamic simulations of the air flows, temperature distribution and contaminant remove efficiencies for typical workstation configurations which include the option for localized supply of outdoor air will be prese
Numerical modelling is performed to predict air movement, thermal comfort level and contamination distribution within an open office space.
Modern inlet devices applied in the field of ventilation of rooms are getting more complex in terms of geometry in order to fulfil the demand for thermal comfort of the occupants in the room and in order to decrease the energy consumption This exp
Recent full scale experiments has detected the presence of low Reynolds number effects in the flow in a ventilated room.
The paper discusses methods to set boundary conditions at the air supply opening in predictions of room air flows with computational fluid dynamics.
Due to the limitations of computer storage and time the flow boundary conditions at an air inlet device have to be specified for numerical simulations of air flow patterns in rooms.
This paper is concerned with the application of air flow simulation in design.
Both infiltration and exfiltration has a predominant influence on the space heating requirements in cold climates. Good predictive design methods are required to estimate the air leakage component in buildings.
Influence of radiative participation of inside air on natural convection in a room. | 1991 | English
The basis of this study are experimental results obtained on a real scale cell in controlled climatic conditions which are used to show the potential influence of radiative participation of inside air on natural convection in a room.
A set of diagrams for estimating flow coefficients and exponents in the power law flow equation for cracks are presented.
A new simple method is proposed here for the experimental singling out of the air flow patterns in a room.
Application of hot wirelfilm ariemometry in room air flows presents difficulties because: (1) the effect of natural convection due to the heated wire beconies significant for low air velocity measurements; (2) the angle sensitivity of a hot wire b
The paper presents an original computer code for the analysis of contaminant diffusion in rooms developed at the Politecnico di Torino and its experimental validation by means of a test facility located at the University of Basilicata (Potenza).
Reverberant sound excitation and the sound intensity technique have been used for the measurement of the sound transmission loss of narrow slits in rigid walls.
Mechanical systems which use common ducts for combined heating and ventilating functions are becoming popular in the Pacific Northwest (U.S.).
As part of the AIVC's technical programme, study has been performed on present and advanced ventilation systems.
