Multi-scale and multi-physics CFD-based computational tools for nuclear applications and the need for CFD-grade experiments (Graduate Seminar)

Event Date: February 19, 2014
Speaker: Prof. Annalisa Manera
Speaker Affiliation: Department of Nuclear Engineering and Radiological Sciences, University of Michigan
Type: Graduate Seminar
Time: 3:30 p.m.
Location: ARMS B071

 

SUMMARY

The application of Computational Fluid Dynamics (CFD) in the development of multiscale and multiphysics coupled tools will be discussed.

The presentation will focus: 

a) the development of a multiphysics simulation tool involving CFD, a neutron transport code and a chemistry code for the high fidelity simulation of crud deposition on PWR fuel rods.

b) the development of a multiscale coupling between the US NRC 1D best estimate-thermal hydraulic code TRACE and computational fluid dynamics, with special emphasis on the appropriate code validation.

The talk will also address the design of CFD-grade experiments aimed at the validation of advanced computational methodologies in thermal-hydraulics.

 

Bio sketch:

Dr. Annalisa Manera, after received a Ph.D. in Nuclear Engineering from the Delft University of Technology (The Netherlands), worked for two years as scientist at the Research Center Rossendorf-Dresden (Germany), before becoming the Head of the group of “Nuclear systems behaviour” in the Laboratory of Reactor Physics at the Paul Scherrer Institute (PSI, Switzerland). With her group providing technical support to the Swiss Nuclear Authority, her research was focused on the development of state-of-the-art methodologies for nuclear plants safety analyses, including coupling between 1D-TH and 3D neutron kinetics, and computational fluid dynamics. Since June 2011 Annalisa Manera is associate professor in the Nuclear Engineering Department at the University of Michigan.Her research interests include experimental thermal-hydraulics, computational fluid dynamics, and multi-physics methods for power reactor safety analysis.
