Using COMSOL® for the Development of the UK’s Second Hyperloop Prototype

A. Jocas [1], I. C. H, Chan [1], A. Malekos [1], H. P. Chan [1],
[1] The University of Edinburgh, UK

Hyperloop is a future concept of mass transportation proposed by Elon Musk. It uses electromagnetic propulsion to accelerate a passenger or cargo pod through a low-pressure tube. HYPED, the University of Edinburgh’s Hyperloop Team has created a prototype that uses linear halbach arrays ... Read More

Modeling the Hyperloop with COMSOL®: on the Design of the EPFLoop Pressurized Systems

Z. Sajó [1], L. Benedetti [1], N. Riva [1],
[1] EPFL - EPFLoop, Lausanne, Switzerland

The Hyperloop is a concept system targeting passenger transportation aiming to carry people in a pod running in a high vacuum tube at 1200 km/h. In 2015, SpaceX announced that they would sponsor a Hyperloop pod design competition, because of their interest in helping to accelerate the ... Read More

Detailed Axial Symmetrical Model of Large-Scale Underground Thermal Energy Storage

A. Dahash [1], M. B. Janetti [1], F. Ochs [1],
[1] Unit of Energy-Efficient Buildings, Institute of Structural Engineering and Material Science, University of Innsbruck, Innsbruck, Austria

Seasonal thermal energy storage (STES) systems are key components for expanding the renewables share in the energy scheme as they offer the dispatchability and flexibility. Therefore, thermal behaviour of such systems is of interest. STES can influence the surroundings causing a ... Read More

Simulation of Laser-Excited Surface Acoustic Waves Travelling on a Steel Hemisphere Shell

J. Mäkinen [1], D. Veira Canle [1], R. Blomqvist [1], A. Salmi [1], E. Hæggström [1],
[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

Non-contacting guided wave tomography based on laser ultrasonic waves can be used to inspect structures that are inaccessible to traditional ultrasound methods. Such structures could be, chemically or physically hard to reach, e.g. hot metal structures, metal implants inside tissue or ... Read More

The Numerical Challenges in Multiphysical Modeling of Laser Welding with ALE

I. Tomashchuk [1], I. Bendaoud [2], J.-M. Jouvard [1], P. Sallamand [1],
[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Le Creusot, France
[2] Laboratoire de Mécanique et Génie Civil, Université de Montpellier, France

The interaction of high power laser beam with metallic materials produces a number of interconnected phenomena that represent a serious challenge for numerical modeling, especially for creation of auto-consistent models. Additional difficulty consists in lack of data on materials ... Read More

Simulation of 1D Heat Distribution in Heavy Oil Reservoirs During Steam Injection Process

T. H. Nassan [1],
[1] Freiberg University of Technology, Institute of Drilling Technology and Fluid Mining Engineering, Freiberg, Germany

Enhanced oil recovery (EOR) is expanding worldwide to produce more oil from the existing reservoirs to fulfil the demand of the global consumption, which increases on yearly basis. Thermal methods like steam injection and its variations are the most famous methods applied in heavy oil ... Read More

Thermo-Fluid-Metallurgical Modeling and Parametric Study of Laser-Based Powder Bed Fusion Process

M. Bayat [1], S. Mohanty [1], J. H. Hattel [1],
[1] Department of Mechanical Engineering, Technical University of Denmark, Lyngby, Denmark

Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... Read More

Modeling Solid-Liquid Settling System as a Two-Phase Flow Problem

L. Gyurik [1], A. Egedy [1], Zs. Ulbert [1],
[1] University of Pannonia, Veszprém, Hungary

Sedimentation is a challenging two-phase problem to model and simulate. Many applications in the industry use sedimentation for separation. For example treatment of wastewater often carried out in settling basins. Different types of the sedimentation process include independent and zone ... Read More

Application for Construction and Numerical Analysis of New Melting Elements

L. Strehar [1], S. Kovač [1], D. Janc [1],
[1] ETI d.o.o., Izlake, Slovenia

ETI is one of the world’s leading manufacturers of fuses. Different standard sizes, rated voltages, rated currents and tripping characteristics mean more than 750 different types of products. Additionally, our customers sometimes require fuses specifically designed for their needs. Our ... Read More

Simulating Approaches for Heating Process in Continuous Furnaces

G. Petrone [1], R. Sinatra [1], C. Barbagallo [1],
[1] BE CAE & Test, Italy

Heating of pieces evolving in tunnel furnaces is an argument of high interest in several industrial processes such as thermal treatment of metals, glass production and food industry.Because of pieces move into the furnace, heat flux they receive from fixed heat sources is variable in ... Read More
