Abstract

In order to prepare for a medium-scale SNIC application focusing on numerical studies of plasma assisted combustion in gas turbines and in supersonic combustors I wish to test the scalability and performance of the solvers to be used in this work. These solvers have previously been extensively used on different high performance computational resources. Hence, this study has the sole purpose of evaluating how these solvers perform and how the work flow can be optimised for the SNIC resources. The planned medium-scale application will support two ongoing research projects: (i) EFFECT (EFFicient Electric Combustion Technology) II, funded by the Swedish Energy Agency under grant agreement No 42555-1, and (ii) STRATOFLY (Stratospheric Flying Opportunities for High-Speed Propulsion Concepts) funded by European Union’s Horizon 2020 research and innovation programme under grant agreement No 769246. More specifically, EFFECT focuses on investigating plasma assisted combustion for gas turbine-like applications whereas STRATOFLY focuses on high-speed dual mode ramjet engines. Both projects were initially managed by the Swedish Defence Research Agency, FOI, but have since January 2020 been reallocated to the Department of Energy Sciences at the Faculty of Engineering, Lund University, LTH, as the Principle Investigator Prof. Fureby has moved from FOI to LTH. Originally, all numerical simulations were carried out at FOI, using in-house resources, but due to the reallocation of these projects computational resources need to be provided from the Swedish National Infrastructure for Computing. For both projects we plan to use reacting flow codes developed using the OpenFOAM platform, versions 2.2.2 and 6, using different numerical schemes. Both codes are designed for finite rate chemistry Large Eddy Simulation (LES), and are intended to be used together with pathway-centric reaction mechanisms, and state of the art sub grid and LES combustion models.
