LoginExperimental set-up and measurement procedures were carried out to evaluate the performance of a windcatcher, using an open working section wind tunnel.
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.
This paper sums up the developments in geophysical fluid dynamics and ocean currents related to dynamical phenomena. Examples from study of ocean flows are given, then several methods for studying nonlinear dynamical phenomena proposed.
Due to the renewal of interest for solar chimneys (that convert thermal energy into the kinetic energy of air movement) , experiments were carried out in a controlled environment, with a full-scale chimney, where both air-velocity and air-tempera
The study of buoyancy-driven natural ventilation in buildings requires windless conditions.
The effect of a solar chimney along with a solar screen on the effectiveness of natural ventilation is investigated in this paper.The benefit of the combination of both systems is that it enhances the natural ventilation flow through the building
This paper is a description of a numerical method that aims at analysing three-dimensional natural convection in rooms with wide openings.A 3D CFD tool is proposed to predict the airflow pattern and the heat and mass transfer inside a heated offic
LES (Large Eddy Simulation) has bben used to simulate cross ventilation under various wind direction angles.
A newly proposed method for evaluating ventilation performance of various types of window openings is presented with its experimental validation. The experimental system has been designed by means of wind tunnel techniques.
This paper is a presentation of a detailed mathematical simulation along with an experimental investigation of airflow in solar chimneys carried out with an experimental apparatus whose most of the variables could be changed during the experiments
This paper studies the climatic suitability to natural ventilation, which depends on energy saved for cooling and on the presence of driving forces such as wind and buoyancy.
This paper aims at developing and implementing a fuzzy controller for naturally ventilated building.The first objective of this research was to develop and then validate a rule based controller which can vary the resistance of ventilation opening
This paper presents the results of the performance of a wall-mounted natural ventilation convector under real winter weather conditions.
The REinforced EXhaust System (REEXS) is a local ventilation principle for industrial ventilation with improved efficiency for capturing contaminants released by working processes .This paper discusses the validation of a 3D CFD model for the dete
This technical note from AIVC aims to provide information on residential ventilation systems and how these can be applied to meet the conflicting needs for fresh air and minimised energy consumption.
The article describes the available techniques for sampling and analysing VOCs emitted by materials.
European radon research and industry collaboration concerted action (ERRICCA2) is establishing a European scientific led industrial forum aimed at reducing risks to health from radiation (principally radon) in the built environment.
The aim of that study was to measure the performance of local ventilation for various parameter settings (nozzles and slots REEXS) and to demonstrate the benefit for real working situations.A test cabin was built, to measure the capture efficienc
This paper aims at showing the difference between the two approaches used to evaluate the capture efficiency of a local ventilation system : an experimental research using the tracer gas method ( CO2) and the numerical modelling using CFD code
One way to prevent cold air from entering through the doorway into a building is to use an air curtain. It is a stream of air blown across the doorway that acts as a thermal barrier.
This paper deals with measurement of the capture efficiency of REEXS (Reinforced Exhaust System).
