Research Expertise

Prof. Groth heads the CFD and Propulsion group at UTIAS. He is a theoretical and computational fluid dynamicist with expertise in high-performance computing/parallel algorithm design, adaptive mesh refinement (AMR), and finite-volume schemes for both compressible non-reacting and reactive flows. He also has expertise in the computation of non-equilibrium, rarefied, and magnetized flows, and the development of generalized transport models and solution methods following from kinetic theory. His numerical method research currently focuses on output-based anisotropic AMR for both steady and unsteady flows, high-order spatial and temporal discretization methods for flows with shocks, complexity reduction via moment closure methods, and data assimilation methods for performing data-driven simulations. He is currently pioneering the development and application of high-order and AMR methods for high-speed compressible flows of gases and plasmas, as well as reactive flows, and the formulation of accurate and robust moment closure techniques for describing a range of micro-physical transport phenomena in non-equilibrium, rarefied gases flows, as well as multi-phase flows associated with liquid fuel atomization and soot formation gas-turbine engines. He is also involved in fundamental numerical studies of laminar flames and the development of reliable and robust numerical techniques for performing large-eddy simulations (LES) of turbulent reactive flows. He has extensive experience in the simulation of gas-turbine combustor flows under high-pressure conditions through collaborative research efforts with industry partners, including Pratt & Whitney Canada, a leading manufacturer of aviation gas turbine engines.
