LoginReports systematic pressure distribution measurements made on models of rectangular buildings of various heights with gabled roofs of different slopes in a wind tunnel. Describes the models and test procedure.
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.
In connection with the revision of the German specification for loads due to wind, DIN 1055, section 4, an extensive review of literature was carried out.
This paper reports the results of measurements of inside surface temperatures on a basic double window arrangement consisting of two sheets of glass surrounded by insulated construction.
Model-scale tests in turbulent wind. part 1. Shelter at houses- dispersal of smoke. | 1963 | English
Describes instrumentation used to measure air flow and pressure. Presents laws for turbulent and laminar flow in a wind tunnel.
Reports measurements of infiltration rates in two research houses in Minnesota under different wind, temperature and inside operating conditions using helium as a tracer gas.
Gives equations and charts for the calculation of heat and moisture flow due to natural convection through openings in vertical partitions separating spaces at different air conditions.
Gives measurements of air infiltration made in ten houses in Indiana using helium as a tracer gas. Assumes linear dependence of infiltration rate on temperature difference and wind velocity and calculates infiltration rate per unit crack length.
Compares methods of calculating ventilation rates in mechanically ventilated animal houses.
Describes the basis of operation of electron absorption detector and the nature and causes of the erroneous and anomalous responses it may generate. Suggests pulse sampling technique asan alternative method of analysis.
Discusses the use of a tracer to measure the dispersal of air pollutants. Suggest use of Freon-12 or sulphur hexafluoride as tracer.
Discusses pressure distribution on buildings. Describes wind tunnel tests on model buildings. Pressure distribution on walls were measured in a constant velocity field and in anartificially produced velocity gradient.
Describes both the macro and micro meteorological structure of strong winds in the earths boundary layer. Discusses the wind speed spectrum, characteristics of mean flow and gustiness and the structure of turbulence.
Reviews some previous work on the measurement of wind pressures at full-scale. Deals with some of the problems arising.
Sets out the similarity requirements which must be observed so that results of wind tunnel tests may be used to predict behaviour of full-scale prototypes in the natural wind. Discusses rigid models, suspension bridges, models of slender towers.
Describes experimental techniques used to produce turbulent boundary layers in a wind tunnel. Gives model law for velocity profile in a turbulent flow over a rough surface.
Describes a method for measuring the radon concentration of three litre samples of atmospheric air without pretreatment. Apparatus used consists of a 12 in. photomultiplier with 2ns (ag) phosphor and counting chamber.
Describes an instrument for the measurement of air infiltration into buildings.
Describes the ventilation of buildings by analogy with electric circuits and derives expressions for ventilation with and without flow through ducts in the roof. Finds that in general ventilation rate will vary linearly with wind velocity.
