Abstract
This report presents the results obtained from a series of flow visualisation and
flow measurement wind tunnel tests, carried out at Glasgow University, on
models of the existing and proposed Kingston bridges. The background to
the tests, commissioned by Strathclyde Regional Council after discussions
with staff from the Department of Aerospace Engineering, is provided in the
Introduction. Details of the facilities employed and bridge representation are
included also. The important experimental consideration of Similarity is
addressed in some detail, with particular reference to the use of appropriate
scaling parameters for flow frequencies and velocities in the vicinity of the
bridges.
Test results are presented firstly in the form of still photographs of the
illuminated smoke traces, with the main features illustrated by the provision of
flow diagrams for each test. Secondly, the more quantitative measurements are
presented as graphs of velocity versus time at a variety of measuring stations.
In addition, selected video records have been made and are available on an
accompanying, indexed VHS cassette.
A detailed discussion of the results is presented, and five main conclusions are
made concerning the structure of the flow around the existing and proposed
bridges
