This outstanding thesis characterises the aerodynamic flow around a
container freight train; investigating how changing container
loading configurations affect the magnitude of aerodynamic forces
measured on a container. 1/25th scale moving-model freight train
experiments were carried out at the University of Birmingham's
TRAIN rig facility to investigate slipstream velocities and static
pressure, as well as measuring, using a specifically designed
on-board pressure monitoring system, the aerodynamic loads on
containers. Results were compared with full scale data and assessed
in terms European standards for trackside worker and passenger
safety limits. Rail vehicle aerodynamic studies have tended to
previously focus on high speed passenger trains in line with
increases in train speed. The research presented within this thesis
highlights the issues associated with the aerodynamic development
around a freight train, providing the foundations for further
research and a basis from which to develop international safety
standards in relation to freight, as well as high speed trains.
Train Aerodynamics: Fundamentals and Applications is the first
reference to provide a comprehensive overview of train aerodynamics
with full scale data results. With the most up-to-date information
on recent advances and the possibilities of improvement in railway
facilities, this book will benefit railway engineers, train
operators, train manufacturers, infrastructure managers and
researchers of train aerodynamics. As the subject of train
aerodynamics has evolved slowly over the last few decades with
train speeds gradually increasing, and as a result of increasing
interest in new train types and high-speed lines, this book
provides a timely resource on the topic.
