Dr Lindsay-Marie Armstrong is Lecturer within Engineering and the Environment at the University of Southampton.

Current position

Lindsay-Marie is a Lecturer in the Energy Technology group within the Faculty of Engineering and the Environment. She is also the Chair of the Faculty's Equality and Diversity Committee and lead for the Faculty's previous Bronze and recent Silver Athena SWAN submissions. In 2015, she initiated and is now Chair of the Clean Carbon University Strategic Research Group (USRG) (more info: She is also deputy Admissions Tutee for the Faculty’s Mechanical Engineering programme and module co-ordinator for the “Thermofluid Engineering for Low Carbon Energy” part IV module.

Career history

Lindsay-Marie graduated in 2006 from Northumbria University in Newcastle with a BSc (Hons) degree in Mathematics. It was there that she developed an interest in the field of fluid dynamics which was pursued further with an MSc in Computational Fluid Dynamics (CFD) at the University of Leeds.

She came to Southampton in 2007 to carry out a PhD project focusing on the multiphase CFD modelling of the gas-solid flow dynamics and thermal conversion processes in fluidised beds. Which explores computational methods for modelling existing combustion processes for coal and biomass. Her PhD led to numerous highly cited articles in highly recognised journals and presentations at numerous national and international conferences. Her work also received an Institute of Physics awards for "Significant contribution to combustion from an early career researcher". Her models were later extended to included SO2 emission control through the inclusion of desulphurisation modelling during her post-doc.

A particular area of interest is carbon capture and how computational models can be used to optimise existing and promote the development of state-of-the-art technologies. She developed a successful research bid very early on to establish a team at Southampton applying multiphase methods to capture the CO2 absorption processes in post-combustion technologies in collaboration with E.ON and Cranfield University.

In 2012, she secured a five year academic track New Frontiers fellowship which gradually introduced her to teaching of various modules, including Thermofluids and Bioenergy. She also gather leadership skills as Chair of the Faculty Equality and Diversity Committee and contributing to numerous other committees such as the University Athena SWAN committee, WiSET (Women in Science, Engineering and Technology), Member of Senate

 In 2014, she proposed the formation of a university-wide research group enabling our global recognised researchers on clean carbon technologies and environmental and climate change to work towards better solutions in a more cohesive structure. The proposal was a success and initiated in 2015 upon her return from maternity leave.

Key statistics: 17 publications, >200 citations, H-index = 8, contributed successful grants: ~£1.5m

Research interests

 Lindsay-Marie is interested in using computational fluid dynamics to improve the performance of industrial energy production processes whilst reducing harmful emissions. Her interests are particularly focused on:

  • Mathematical modelling
  • Computational fluid dynamics
  • Multiphase modelling - particularly kinetic based granular flow modelling
  • Granular systems in biomedical engineering

Research project(s)

Reactive multiphase granular flow

Granular systems are ubiquitous across the industrial and environmental sectors so it is essential to develop methods that not only capture the granular behaviours accurately but also can be used to enhance industrial processes.

Optimisation of Carbon Capture and Storage Technologies

EU - China Cooperation for Liquid Fuels

ECOFUEL is building an international partnership for new second generation biofuel processes: the research will set the foundation stones for the technologies being developed, and make further contributions to overcoming barriers to commercialisation. The ECOFUEL project will effectively integrate respective regional programmes for better allocation and utilisation of resources, in particular to achieve the critical mass required to move the second generation of biofuels forward.
