A wind tunnel study of the mean pressure forces acting on large groups of low-rise buildings.

Presents the results of a series of wind tunnel tests in which the surface pressure fields of low-rise buildings have been studied. These tests start with an examination of how the body shape influences the surface pressures for a range of isolated bodies. The test results then go on to describe how theparameters which describe an array of such model buildings influence the surface pressures. Both the body form and the array form have been widelyvaried in order to formulate design information which covers a practical range of built form planning requirements.< The results demonstrate the possibility of describing the surface pressures on groups of low-rise buildings in terms of three types of flow regime known to exist for the flow over general arrays of roughness elements on a surface.
