Lecturer, College of Engineering
Dr Ben Evans is a lecturer in Aerospace Engineering and sits on the design team for the BLOODHOUND SSC Land Speed Record project. Dr Evans's research interests range from computational shape optimisation and high speed aerodynamic modelling to molecular gas dynamics simulation. He also has interests in engineering public engagement and engineering education.
Dr Evans is a director of the Engineering Education Scheme in Wales (EESW)
Dr Evans’ research in computational fluid dynamics has been largely in high speed aerodynamics and particle entrainment with application to the BLOODHOUND SSC Land Speed Record vehicle. His interests and publications in this area range from numerical methods for solution of the compressible Navier-Stokes equations to data visualisation techniques and enhanced post-processing of CFD datasets for use in aerodynamic design. Much of Dr Evans’s research makes use of the Swansea University FLITE3D CFD system and high performance parallel computing.

Dr Evans has interests in the use of finite element methods for the solution of the governing equation of molecular gas dynamics, the Boltzmann kinetic equation. This non-continuum approach to studying fluids considers a gas at the molecular level before trying to recover macroscopic gas properties. Applications his work in this area have included hypersonic rarefied gas flows over re-entry space vehicles and microscale modelling.
Molecular Gas Dynamics involves the consideration of a fluid in terms of the motion of the individual molecules

Dr Evans’s work on the design of the BLOODHOUND SSC land speed record vehicle has led to pioneering research in the field of aerodynamic design optimisation utilising methods including Design of Experiments, reduced order modelling, novel mesh movement techniques and genetic optimisation algorithms.

Dr Evans has research interests in engineering education practice. He has undertaken projects to investigate the impact of the use of integrating a variety of social media into undergraduate education with publications in the HEA Engineering Education journal.

Dr Evans is heavily involved in connecting College of Engineering research with the general public and with schools in particular. He has developed a schools show that visits schools across the UK throughout the academic year based on communicating the science behind the BLOODHOUND SSC Land Speed Record attempt. His team also delivers workshops in which school pupils design, build and test their own rocket propelled cars.

Dr Evans also regularly gives public talks and lectures about his research. He has been invited to speak at Cheltenham Science Festival on topics ranging from Land Speed Record racing to fuel efficient flying, Cardiff Science Festival and British Science Association events amongst many others. If you would like to contact Dr Evans about speaking engagements please email him directly at email@example.com or contact him on Twitter @DrBenEvans
Dr Evans and his team have partnered with engineers based at M.I.T. in the USA to develop a web-based interactive CFD solver called aerodoodle. This is primarily an education tool to help people understand the capabilities of CFD solvers in a fun and interactive environment on the web.
