LoginIn this paper the application of CFD simulation with unstructured fine elements system was carried out to obtain airflow data for the boundary conditions for an air flow.Tthe results were compared with the measured data.
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 main objective of this paper is to describe methods for characterising air diffusers for CFD simulation of the room airflows. As a basis of work, a circular diffuser was used for working out and testing those methods.
Model experiments were conducted to know the airflow in a room equipped with a ceiling multi-cone diffuser A comparison between the results of CFD and the model experiments has been done.
This paper deals with the integration of CFD analysis tool with genetic algorithms. This integrated process presents advantages in generating design alternatives that tally with multiple design, thermal and ventilation criteria.
This article presents the new requirements of the ANSI/ASHRAE standard 62-2001, Ventilation for Acceptable Indoor Air Quality, including recent changes of the standard available at the Ashrae web site.
Ventilation strategies for multiunit residential buildings are described according to the results of a survey in 260 randomly selected buildings in Canada.
The article summarizes the results of three recent Danish studies showing that the improvement of air quality in offices increases productivity by 5% or more.
The methods for estimating or calculating the noise reduction in ductwork are described. Information is given about noise propagation in straight circular or rectangular ducts and in ducts with diameters changes, bends, elbows or junctions.
Numerical modelling of particle dispersion within a displacement ventilation system | 2002 | English
This paper deals with a 3D numerical study to assess the effectiveness of a displacement ventilation system to remove particulate pollutants, generated in the occupied zone of a room.
Flow, temperature field and contaminant concentration distributions are analyzed using CFD for 5 different ventilation systems.
This paper presents a numerical method aiming at recreating the concentration field of a pollutant at each point of a ventilated enclosure that contains one or several pollutant sources of unknown emission rate.
This study consisted first in a sampling campaign that has shown the important levels of NCL3 encountered in swimming pools.
When using RANS turbulence models the mean profiles of mixed convection can be predicted with accuracy.
The aim of this work was to develop a new calculation method of the zonal air velocity in ventilated room during the design stage. The verification showed a good correlation between the method and the experimental data.
The study used CFD to examine reactions between ozone and terpenes in a room under 4 conditions.
CFD is a suitable tool to calculate concentration in particle contaminant distribution in a room. 3 approaches are described for two types of flow problems and compared in this paper.
This paper presents a universal but simple mathematic model very useful to predict Volatile Organic Concentration in the bulk air for different conditions in residential buildings.
Using the model developed in part 1 of this paper, the influence of material kinds, ventilation and air-cleaning device on VOC concentration in room is studied.
In this study, an office with mixing ventilation is considered. The CFD analyses show that for high cooling loads it is useful to couple a cold ceiling to primary air system
This paper deals first with experimental measurement performed in a test chamber to investigate the characteristics of temperature and moisture distributions. The effect of moisture accumulation in building material is studied too.
