wind tunnel

Describes experiments carried out by the Danish Maritime Institute using data from the Aylesbury experiments of the UK Building Research Establishment. The simulation of the standard rural terrain and the Aylesbury terrain was achieved by mea

General principles of air movement around buildings are stated, indicating where windy areas are likely to occur. Case studies are then described in detail, and lessons to be learnt from these are summarised. Descriptions of wind tunnel measurements around simple model buildings are followed by accounts of the use of meteorological wind data and of the effects of wind on people. A method of predicting wind conditions around a building is developed. Some notes on wind tunnel investigations are given.

This paper reviews the most recent research on wind loads on low-rise buildings. Novel measurement techniques and methodologies are reviewed, and selected experimental results from various studies are presented. Particular emphasis is given to works aimed at the formulation of codified data, ie,results appropriate for incorporation into design standards and codes of practice. Only either full-scale studies or those done under conditions simulating the earth's atmospheric boundary layer have been considered. Comparisons between full-scale and laboratory results are discussed.

The appearance of bubbles used for flow visualisation around bluff bodies in a wind tunnel is illustrated. It is demonstrated that the large diameter and low density properties of bubbles could enable them to represent raindrops in a wind tunnel.

Gives detailed results of an extensive programme of wind tunnel testing of a standard scale model of a one-room, flat-roofed building. A major requirement was coverage of those characteristics of window openings or window accessories which were known (or which appeared) to have a significant effect on indoor air flow.

A systematic series of tests measuring probable distribution of wind pressure on buildings over a practically useful range of building proportions was undertaken using a three dimensional tunnel on a wide assortment of simply gabled block type structures. These tests were then extended to thinwalls, hangar type structures, and simple building groups. The possible effects on building codes and construction techniques are discussed.

The pressure drop and flow characteristics of short capillary tubes have been investigated experimentally for length-to-diameter ratios varying from 0.45 to 18 at diameter Reynolds numbers ranging from 8 to 1500. In the range of the dime

Although there has been an increasing use of wind-tunnel tests on models to examine the structure of wind around buildings, there has been surprisingly little research into the correlation between the results of such studies andthe wind pattern around the full scale structures. This report gives the results of a comparison between the wind flow about a relatively open area of the city of Liverpool, as measured by the relative exposures of twelve field anemometers, and the flow observed in a 1:500 scale model of the same area immersed in a profiled, turbulent, wind tunnel flow.
