Dr Louisa Michael
PDRA Alumna
Louisa Michael's research is primarily on multi-physics, multi-material, multi-scale and multi-phase problems. In particular, she is interested in developing appropriate governing equations and associated numerical algorithms to accurately simulate such systems. She focuses on the form of the equations that allow the simultaneous solution of Euler, reactive flow and elastoplastic systems of equations on the same grid, with the same finite volume methods. She is also developing mixed Riemann solvers for such systems to ensure the correct communication of information across material interfaces. Of particular interest are also combustion problems and their mathematical representation and numerical solution. Latest interests include numerical modelling of explosively generated electromagnetic effects and plasma arc induced detonations.
Louisa has worked on numerous industrial funded applications including: sensitization of condensed-phase explosives (ORICA), multi-material modelling (Qinetiq), multi-phase flows and fluid-structure interaction (Schlumberger), HPC & Simulation Knowledge Mining and Abstraction, wading, internal combustion engines, crash and fuel initiation (Jaguar LandRover).
