Practical Introduction to Computational Fluid Dynamics: Turbulence Modeling and Reynolds Averaged Navier Stokes

Computational Fluid Dynamics (CFD) is increasingly used within the nuclear industry and research centers for a variety of tasks. Yet, despite its widespread use, CFD has many pitfalls that should be avoided in particular when modeling complex turbulent flows. After Introducing Nek5000 in a recent webinar – a powerful open source code, we embark in a four lecture webinar series on CFD. The aim of this short series is to introduce key concepts in turbulence modeling with a focus on practical applications in nuclear engineering. The first lecture will cover Reynolds Averaged Navier Stokes or RANS turbulence models, which are currently the workhorse of CFD in industry.

Presenter

Annalisa Manera, Professor of Nuclear Systems and Multiphase Flows, ETH Zurich

Since July 2021, Dr. Manera is on a leave of absence from the University of Michigan, where she has been Professor in the Nuclear Engineering Department for the last 10 years. At the University of Michigan she has established a research and teaching program in nuclear systems thermal-hydraulics and is the co-director of the Experimental and Computational Multiphase Flow Laboratory (ECMF) and the High Resolution Imaging Lab. Her research group focuses on high-resolution experimental techniques and CFD-based high-fidelity multiphysics simulations of nuclear systems.
