Wind Engineering

  • The Birmingham Tornado
  • Wind blown tree damage

I have worked in the field of wind engineering and bluff body aerodynamics throughout my career, largely concerned with the intermediate wind speed range between the low wind speeds of relevance to ventilation and wind energy studies, and the high wind speed range of most relevance to structural design. Thus the main thrust of my work has been in the fields of sustainability and resilience – how to make structures and infrastructure and agricultural systems safe, reliable and fit for purpose. This page contains links to blog posts and presentations in this area.  In addition links to recent papers and student PhD theses are also given.

International Wind Engineering Seminars

A series of International Wind Engineering Seminars, sponsored by the IAWE, are being held between October 2020 and March 2021, via Zoom. Full details can be found here.

Wind Engineering papers

The links given below are to the publishers’ web sites, where the abstract can be read and the publication downloaded with the necessary permissions. Alternatively the final pre-publication of many (but not all) of these can be found the Birmingham Electronic Paper Repository here. Note also that many of the papers on the Train Aerodynamics and Transport pages also have a high Wind Engineering content.

Wind Engineering presentations

This presentation looks at the oldest world sporting record – that for throwing the cricket ball that dates back to 1882. It was originally produced for a conference of academic aerodynamicists that didn’t take place and contains both historical and technical material. A written version is given in the blog post The oldest world record – Robert Percival’s 1881 cricket ball throw
This video describes a series experiments to measure pedestrian behaviour in high winds, through the use body and foot mounted instrumentation. The work formed part of a wider EPSRC sponsored project to investigate the safety of pedestrians, cyclists and vehicles in urban areas in high winds. A blog post on these tests can be found at Measuring the behaviour of pedestrians in high winds
