Teaching

  • EG-M90 Advanced Aerodynamics

    This module is intended to extend the theory of EG-293 Aerodynamics & EG-335 Gas Dynamics and apply it in the context of aerodynamic design across a range of length scales and Mach number. A number of case studies will be used to explore the concepts of aerodynamic design ranging from subsonic civilian aircraft to aerodynamic design in nature and hypersonic space vehicles. The course is split into four sections: subsonic, transonic, supersonic and hypersonic. By the end of the course students should have developed a good understanding of why aerospace vehicle operating in these different speed regimes with varying mission objectives look the way do from an aerodynamic perspective.

  • EGA302A Aerospace Engineering Design 3

    The module is a group design project for level 3 aerospace engineering students. Students are required to design an aerospace vehicle from an initial set of mission requirements and constraints through concept design to detailed design and flight testing. It requires students to draw on knowledge from a range of modules across the aerospace engineering course. Each student will specialise in one of six areas: aerodynamics, structure, materials & propulsion, weight& performance, control systems or dynamics & stability. Groups will be required to submit a series of design reports at each stage in the design process as well as deliver presentations to the rest of the class. Each student will also take a turn acting as chief engineer and a reflective essay is required after the student's time as the chief engineer. By the end of the module students should have an understanding of the process and complexities involved in designing an aerospace vehicle from scratch and appreciate the multi-disciplinary nature of this task.

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.

Invited talks

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 b.j.evans@swansea.ac.uk or contact him on Twitter @DrBenEvans

Aerodoodle

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.

Engineering Education

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.

Interactive teaching

Incorporation of YouTube and Twitter into the HE learning and teaching environment.

Computational Fluid Dynamics

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.

Molecular Gas Dynamics

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.

Molecules

Molecular Gas Dynamics involves the consideration of a fluid in terms of the motion of the individual molecules

Vehicle Re-entry

Shape Optimisation

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.
