In my current role as a Research Software Engineer and High-Performance Computing Consultant, I optimse the performance of complex scientific codes across a range of projects. These scientific codes are utilised for research within the departments of Physics, Chemistry, and Engineering.
Report on performance and scalability of OpenFOAM and Cloverleaf, two CFD applications, on the ARM platform.
Also on HPC Wire.
The ignition of condensed-phase explosives is investigated by simulating the reflection of a shock through nitromethane. The passage of the shock leads to the formation of a reaction wave. Of particular interest is the evolution of the reaction wave from when it emerges to when it eventually overtakes the precursor shock. We identify, locate and characterise transient, quasi-steady phenomena in the unsteady flow prior to the formation of a steady detonation wave. Results indicate that the reaction wave is composed of transient, quasi-steady waves similar to the ones observed in the gaseous case, albeit in a more complex combination.
