Dr David Soper is a Lecturer in Vehicle Aerodynamics in the School of Engineering and Birmingham Centre for Railway Research and Education. His research interests lie in the field of applied fluid dynamics and engineering applications through vehicle aerodynamics. He has particular expertise in experimental investigations both at model and full scale. He is the facility manager and operator of the University of Birmingham moving model TRansient Aerodynamic INvestigation (TRAIN) rig for vehicle aerodynamic research.

David completed his PhD in the field of freight train aerodynamics before becoming a Research Fellow at the University of Birmingham, carrying out a range of academic and consultancy projects at the TRAIN rig. He has been an investigator on projects for EPSRC, BBSRC and industry funded work for many organisations including Arup, Network Rail High Speed, Railway Accident Investigation Branch, Network Rail, Bombardier. This work has include complex full and model scale measurement campaigns supporting high profile project, such as the Twyford aerodynamic incident involving a wheelchair, Crossrail and HS2. Further information can be found at TRAIN RIG LINK.

The results of this work have been published in over 10 research papers in scientific journals and a similar number of conference presentations.

Qualifications

PhD in Civil Engineering 2014
MSc in Theoretical and Applied Fluid Dynamics 2010
BSc (Hons) Mathematics 2009

Biography

Dr Soper read Mathematics and Theoretical and Applied Fluid Dynamics at the University of Manchester before undertaking a PhD in Civil Engineering at the University of Birmingham. His novel PhD used the TRAIN rig to look at the aerodynamics of a container freight train, and for the first time was able to characterise key aerodynamic flow characteristics of freight trains. After successfully completing this work he remained at the University of Birmingham as a Research Fellow for 3 years working on a wide range of multi-disciplinary projects funded by EPRSC and BBSRC, as well as industrial funded projects including the aerodynamic incident at Twyford Station in which a wheelchair was drawn into the side of a passing freight train.

Dr Soper took up his position as a lecturer in the School of Engineering in 2017. Since taking on this role he has been involved in a wide range of research and teaching activities. He has continued to work on a range of purely academic research in the field of wind engineering and vehicles aerodynamics, as well as industry funded projects.
