The flow rate in thermal plumes are influenced by many factors. Influence by enclosing walls is one of them.
Kofoed P, Nielsen P
Sandberg and Skaret differentiate between the terms air change efficiency and ventilation effectiveness.
Brouns C, Waters J
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.
Allard F, Inard C, Draoui A
The airflow pattern and thermal comfort in a naturally ventilated classroom were predicted using CFD techniques.
Croome D, Awbi H, Yusof M, Gan G
As part of the AIVC's technical programme, study has been performed on present and advanced ventilation systems.
Knoll B
This paper extends the integral mass balance approach to the remaining constant concentration technique.
Axley J
This paper is concerned with the application of air flow simulation in design.
Hensen J, Hand J, Clarke J
The concentrations of indoor pollutants should be maintained below recommended values at all occupied locations at any time.
Han H, Kuehn T, Ramsey J
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.
Oldham D, Zhao X, Sharples S, Kula H-G
The paper discusses methods to set boundary conditions at the air supply opening in predictions of room air flows with computational fluid dynamics.
Heikkinen J
Within the frame of the IEA Annex 20, laboratory and numerical experiments were conducted in order to study the flow within an isothermal parallepipedic testroom (L x W x H = 4.2 m x 3.6 m x 2.5 m).
Biolley F, Fontaine J, Rapp R, Serieys J
The performance of a system for demand-controlled ventilation was investigated for a period of 1.5 years. Presence sensors of the passive infrared type are used to control the ventilation rate in each classroom.
Norell L
This paper describes the application of numerical models to predict the ventilation rate and internal air movement patterns for a naturally ventilated industrial building and compares the results with measured data.
Jones P, Alexander D, Powell G
A new algorithm for the continuous measurement of variable air change rates with tracer gases will be presented. It differs from the constant concentration method by allowing the concentration level to vary according to the air change rate.
Rabenstein R, Heidt F D
Knowledge of air movement within a building is often a condition for solving problems with the spread of pollution.
Kvisgaard B, Schmidt L
Tracer gas tests were conducted on a five-storey apartment building to determine the air and contaminant flow patterns within the building.
Shaw C, Reardon J, Said M, Magee R
Airflow rates are directly affected by the amount of open area and consequently by the inhabitant behavior with respect to window opening.
Roulet C-A, Scartezzini J,Cretton P, Fritsch R
A literature search was performed to gain as much knowledge as was available on ventilation, indoor air quality sensors and demand controlled ventilation (DCV) strategies.
Hamlin T, Cooper K
This speech comprises a summary of two publications from the Swedish Council for Building Research (BFR); the knowledge survey "Buildings and Health" (BFR T4:90) and "Indoor climate and energy husbandry" (BFR G5:90).
Kronvall J
Zonal models are a promising way to predict air movement, in a room with respect to comfort conditions and gradient of temperature, because they require extremely low computer time and may be therefore rather easily included in multizone air movem
