High-Resolution FSI Modeling of a High-Aspect Ratio Involute Flow Channel in the HFIR at ORNL

A. I. Elzawawy [1], J. D. Freels [2], F. G. Curtis [2, 3],
[1] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA
[3] University of Tennessee, Knoxville, TN, USA

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid ... En savoir plus

Biologic Tissues Properties Deduction Using an Opto-Mechanical Model of the Human Eye
