Modernization of the High Flux Isotope Reactor (HFIR) thermal-hydraulic (TH) design and safety analysis capability is an important step in preparation for the conversion of the HFIR core from a high enriched Uranium (HEU) fuel to a low enriched Uranium (LEU) fuel. Currently, an important part of the HFIR TH analysis is based on the legacy Steady State Heat Transfer Code (SSHTC). The SSHTC is a ...

The study presents first authors experience with COMSOL Multiphysics environment used as a possible modeling tool of thermal building behavior. The idea of the project was to gain thermal response to changed boundary conditions with the application of COMSOL environment as a modeling tool for 3D buildings or 3D building segments. The room as building segment was implemented in the COMSOL ...

This paper presents some results of numerical simulations carried out to investigate the basic hydrodynamic interactions between the laminar flow in the water column above triangular bedforms and the Darcian flow in the underlying permeable sediments. The flow was described by the Navier-Stokes equation in the free region and the Darcy equation in the porous region. Numerical simulations were ...

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

A compacted bentonite clay buffer is planned to be used as a part of the engineered barrier system in the KBS-3 concept for the disposal of spent nuclear fuel. Simulations together with experimental studies are needed to ensure that bentonite fulfills its safety functions in the concept. In this paper, one type of bentonite model, namely a thermomechanical model developed by Jussila, is presented ...

In the inspection of steel products with respect to flaws a magnetic flux leakage (MFL) test procedure can be applied. In this procedure a “horseshoe” shaped yoke is used, whose legs are wrapped with coils through which an alternate current with a high frequency (3 kHz) is flowing. Hereby a thin magnetic field is induced near the surface of the test object which leaks from the material if a ...

This paper presents a finite element method based modeling and design of control for distributed parameter systems. First, models of distributed parameter systems in the form of lumped-input/distributed-output systems and structure of control loop are introduced. Next, modeling of temperature fields of the casting die as distributed parameter systems in preheating process is performed in COMSOL ...

In this work the issue of saturation phase erosion caused by groundwater leakages was approached both experimentally and computationally by employing COMSOL\'s Earth Science Module. We evaluated the total mass of eroded bentonite out of a cylindrical erosion channel both numerically and experimentally, and studied its dependence on time. It was observed that logarithmic eroded mass loss as a ...

Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples.
