Numerical Modeling and Performance Optimization Study of a Dehumidification Process in Nuclear Waste Storage

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

One of the main parameters to consider during the nuclear waste storage design phase is the drum corrosion risk. The humid-air corrosion models available in literature predict that, for carbon steel, the phenomena start to become appreciable for relative humidity (RH) values close to ... Read More

Comparison Between Phase Field and ALE Methods to Model the Keyhole Digging During Spot Laser Welding

V. Bruyere[1], C. Touvrey[1], P. Namy[2]
[1]CEA-DAM, Is-sur-Tille, France
[2]SIMTEC, Grenoble, France

Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... Read More

Thermal Analysis for the Solar Concentrating Energy and Induction Heating for Metals

A. Rojas-Morín[1], Y. Flores-Salgado[2], A. Barba-Pingarrón[1], R. Valdéz-Navarro[1], F. Mendéz[1], O. Alvarez-Brito[3], M. Salgado-Baltazar[1]

[3]Programa de Posgrado en Ingeniería, Universidad Nacional Autónoma de México.

In this paper, we simulated the heating of a work piece by coupling two heat sources. Concentrated solar energy was applied at the bottom of the work piece, which generated a heat flux from the parabolic solar dish concentrator. Subsequently, induction heating was applied, which ... Read More

Simulated Rheometry of a Nonlinear Viscoelastic Fluid

A. Czirják[1], Z. Kőkuti[1], G. Tóth-Molnár[1], P. Ailer[2], L. Palkovics[2], G. Szabó[1]
[1]University of Szeged, Szeged, Hungary
[2]Kecskemét College, Kecskemét, Hungary

In certain cases, the accuracy of measurements with a rotational rheometer can be influenced by inefficient thermal management, by the heat generated in the sample, or by rod-climbing due to the Weissenberg effect. We investigate the effect of these phenomena with simulations in COMSOL ... Read More

Reducing Solar Heat Gain from Inclined Buildings’ Roof by Using Radiant Barrier System

S. Ebrahim[1], A. Alshayji[1]
[1]Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait City, Kuwait

The study produced a simulated model of natural convection in an inclined rectangular channel open ended with different locations of radiant barrier (RB) along the channel thickness(S). The upper plate is heated by various uniform constant heat fluxes while the inner surface of the lower ... Read More

Optimal Heat Sink Fin and Cold Lid Heights for Liquid Immersed Servers

A. Almaneea[1], J. Summers[1], H. Thompson[1], N. Kapur[1]
[1]University of Leeds, Leeds, United Kingdom

The system in this study is a closed server filled with Novac dielectric cooling liquid. The aim of this study is to find out the optimum value of the fin height and the cold lid height in order to reduce CPU temperature. A mesh accuracy investigation was conducted. The model set up in ... Read More

Multiscale Modeling of Polymer Crystallization

R. Spina[1], M. Spekowius[2], C. Hopmann[2]
[1]Dept. of Mechanics, Mathematics and Management (DMMM), Politecnico di Bari, Bari, Italy.
[2]Institute of Plastics Processing (IKV), RWTH Aachen, Aachen, Germany.

The manufacturing of high quality injection molded parts requires a deep understanding of material properties, process parameters and product design. The behavior of a polymer during the injection molding process and the performance of the final part are strongly determined by the ... Read More

Moisture Risks in Multi-layered Walls - Comparison of COMSOL Multiphysics® and WUFI®PLUS Models with Experimental Results

A. Ozolins[1], A. Jakovics[1]
[1]Laboratory for Mathematical Modelling of Technological and Environmental Processes, Riga, Latvia

Moisture can cause serious damages in different building components therefore the heat and moisture calculation in building constructions are important tasks. In the current paper, two different multi-layered walls, mainly consisted of wooden materials and mineral wool, are analyzed. ... Read More

Modelling Reservoir Stimulation in Enhanced Geothermal Systems

G. Perillo[1], G. De Natale[2], M.G. Di Giuseppe[2], A. Troiano[2], C. Troise[2]
[1]University of Naples Parthenope, Italy
[2]INGV - Osservatorio Vesuviano, Naples, Italy

Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then ...

Modeling the Heat Exchange in Cavities of Building Constructions Using COMSOL Multiphysics®

J. van Schijndel[1], B. Kersten[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Double walls provide stability to the structure and separate the controlled indoor climate from the outdoor fluctuating environment. In this study we want to receive more insight in the heat exchange between the walls through the cavity in between, by computer simulations and ... Read More
