High Fidelity Simulation of Swirl Stabilized Combustor with a chocked outlet

Lead Research Organisation: University of Edinburgh
Department Name: Sch of Engineering


The development of clean, sustainable energy systems is one of the grand challenges of our time. Most projections indicate that combustion-based energy conversion systems will remain the predominant approach for the majority of our energy usage. In the race to satisfy the competing objectives of high fuel efficiency and low emission of pollutants, combustion systems are being driven ever closer to the limit at which the combustion process becomes dangerously unstable, or produces unacceptable levels of noise.

Combustion instability and combustion noise emerge as grand challenges for societal and environmental problems. Combustion instability especially stands out as the single most important problem hindering the development of clean, robust combustion systems (Huang and Yang, 2009).

The central goal for the PhD studentship is to establish the state of the art in high-performance computational simulation. The project will create a new computational simulation tool for engineering research in systems involving turbulence, mixing and chemical reaction. Exploiting ongoing developments in supercomputing, the objective of this project is to use the new simulation tool to provide a comprehensive modelling and design approach that can eliminate instability and noise during the design of cleaner combustion systems.

Title High-fidelity numerical sovler for reacting flows 
Description A novel numerical solver for chemically reacting jets and plumes in a configuration tailored to minimise computational cost. The solver uses a cylindrical geometry, more suitable for flows such as jets and plumes than existent Cartesian coordinate flow solvers. Furthermore, the numerical solver is optimised to make efficient use of today's highly parallel supercomputers, with very good scaling capabilities. 
Type Of Technology Software 
Year Produced 2019 
Impact So far it undergoes further validation, before it will be used for a new high-fidelity simulation of a swirling jet. Afterwards, it will be made available within the UK Consortia on Turbulent Reacting Flows (UKCTRF).

Part Of Official Scheme? No
Geographic Reach International
Primary Audience Undergraduate students
Results and Impact ~40 prospective CDT (Centre for Doctoral Training) students visited Edinburgh University. I gave a presentation about the computational facilities available at the university (e.g. supercomputers) and the training opportunities available to use them. The presentation raised significant interest from prospective students, passionate about numerical modelling for renewable energy.
