LoginA one-dimensional unsteady flow model with a moving pollutant source is used for calculating airflow velocity and pollutant distribution inside the single-track railway tunnel when a train passes through it.
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.
Thermal comfort field studies were conducted in three different sessions (morning, afternoon and night) of the day to evaluate the actual thermal comfort perception of the occupants.
In accordance with the regular and irregular variation principle of high-rise building wind pressure with the variation of time, wind direction proposed in associated reference and high-rise building around flow aerodynamic characteristic.
This paper founds the procedures of standard summer meteorological parameters in hot summer and cold winter region, determines the hourly meteorological model of dry and wet temperature change for sunny days, cloudy and rainy days, and builds up C
On the bases of the definitions of air conditioning period, dehumidifying period and heating period, this paper puts forward to the exchanging conditions and psychometric process of ventilation system in residences.
Ventilation effectiveness is an important means to describe and evaluate the performance of a ventilation system.
A large part of the housing stock in the Netherlands is ventilated badly. Exhaust systems do not work according to building standards. Bad design, bad maintenance and deterioration give a reduction in exhaust volumes of more than 50 %.
Based on the literature and our long-term investigations on indoor environment, the heat source patterns (distribution, location, size, etc) have a predominant effect on temperature efficiency as well as ventilation effectiveness.
In modern buildings, smoke control systems are integrated into the air supply systems. It is possible that the design of the smoke control system will dominate the design process of the air supply system.
In large buildings, pollutants may be emitted locally and discontinuously what can result in time dependent heterogeneous pollutant concentration fields.
By using the technique of turbulent large eddy simulation (LES) and finite element method (FEM) of computational fluid dynamics (CFD), the three dimensional flow fields in vector flow clean-room under empty state and static state condition were pr
A mathematical model has been set up for the multizone structure region in this paper. By the way of numerical simulation, the analyses are conducted of air flow and aerosol particle travel under the mechanised ventilation condition.
Airflow pattern in an indoor sports hall of 17,325 m3 located in the sports complex of City University of Hong Kong has been investigated by computational fluid dynamics technique.
Natural and hybrid ventilation concepts are today the mean items of some international researchers about the behaviour in the innovative buildings. In fact they are utilised to contribute to the thermal comfort and the indoor air quality control.
The context of this work is the development of tools of thermal design adopted in the act of architectural design process, and the difficulty of architects and designers find when using these tools in the analysis of thermal performance of buildin
A hybrid cooling system using radiational panel cooling with wind-induced cross ventilation in an office setting is investigated.
An experimental study of the thermal performance of an air flow window with triple glazing is described. The measurements were carried out in a climatic chamber under conditions close to a winter season.
'Fan in wall' is a new ventilation system under investigation for hot and humid climate to assist natural ventilation.
The sessions in this conference covered: moisture control performance measurements; from the basement to the roof; moisture model inputs; wall design and building science; moisture model validation; wall performance; applied heat and moisture mode
Mould, wet insulation, wet or weakened wood or premature aging of roof coverings often leads to the addition of extra ventilation in attics at time of renovation.
