Propagator-moments approximation for recurrence CFD: application to species transport in turbulent flows
In his first paper, my PhD student Hannes employed the propagator formalism to establish a theoretical framework for transport-based recurrence CFD. Not only can we simulate transport processes, e.g., in turbulent flows faster than real time, now we also understand why. In the course of these theoretical developments, Hannes managed to determine a correction term for numerical diffusion in rCFD which makes simulation results also more accurate than those in our previous studies.
