Aerothermal Simulation of a Refrigerated Truck Under Open/Closed-Door Cycles

P. Namy [1], A. Oury [1], M. Youbi-Idrissi [2],
[1] SIMTEC, Grenoble, France
[2] AIR LIQUIDE, Jouy en Josas, France

Heat transfer inside a refrigerated truck is a key phenomenon that governs the temperature inside the truck and the regulation of the cooling system. Up to now, a lot of experimental studies ([Tso et al., 02]) have been carried out to assess the effect of opening the door and to minimize ... Read More

COMSOL Multiphysics® Simulation of the Electrokinetic Effect in Gidrogeology

M. A. Narbut [1], K. V. Titov [1], P. K. Konosavsky [1],
[1] Saint Petersburg State University, Saint Petersburg, Russia

The groundwater flow is accompanied by the electric field with potential called usually the streaming potential or the Self-Potential (SP) to be measured on the ground surface (e.g., Rizzo et al., 2004; Bolève et al., 2007; Jardani et al., 2009). We studied numerically the SP signals ... Read More

Capillary Flows: Dynamic and Geometry Effects

[1] Department of Biotechnology, CEA/Université Grenoble-Alpes, Grenoble, France
[2] LGP2, Grenoble-INP Pagora, University of Grenoble, Saint-Martin d'Hères, France

INTRODUCTION: Point-Of-Care (POC) and home care systems are of growing importance in biotechnological and medical applications [1]. These devices allow health monitoring directly at home or at the doctor’s office. Portability, low-cost, easy handling and compatibility with telemedicine ... Read More

Improvements on Cyclotron Gas Target Cooling System Using COMSOL Multiphysics® Software

F. M. Alrumayan [1], Q. Akkam [1], S. Alqaryan [1],
[1] King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia

Medical Cyclotrons are used in hospitals to manufacture radiopharmaceuticals. The nuclear reaction between the Cyclotron charged particles and a material takes place inside the so-called targets. In particular, gas target is used when a specific gas is bombarded with proton particles to ... Read More

Cooling Study of Baffles Integration in the Molding Industry

B. Noailles [1] , S. Meunier [1], V. Bruyere [2]
[1] RocTool, Savoie Technolac, Module R, France
[2] SIMTEC, France

In the molding industry, high productivity rate, low energy consumption, large 3D parts, and homogeneous temperature distribution are the main targets. The 3iTech® inductive technology developed by RocTool ensures both good temperature homogeneity and short heating time. Conventionally, ... Read More

Simulation of Gas Injection with the Level Set Method

J. E. Rivera-Salinas [1], A. Cruz-Ramírez [1]
[1] National Polytechnic Institute - ESIQIE, Department of Metallurgy and Materials, Mexico

The physical mechanisms that operate in gas injection are complex, since the bubble formation at submerged orifices involves a wide range of length and time scales, bubble coalescence occurs, rapid pressure variations around the gas bubble produce the wobbling of the bubble, as well as ...

Air Bubbles Motion Through Fresh Concrete During Concreting Process

E. Chuta [1], J. Jeong [2],
[1] Université Paris-Est, IRC-ESTP, Cachan, France
[2] IRC-ESTP, Cachan, France

Over the last years, the concrete technology has progressed in order to improve the quality of its use and mechanical performances. Despite the technical development known in the context of concrete, the esthetic aspect remains weakly treated. Among the esthetic problems, there is the ... Read More

CFD Analysis of a Heat Exchanger for an Electric Machine

[1] ABB S.p.A. Italy
[2] Università degli studi di Pavia, Italy

In recent years the thermal behavior of electric machines is an attractive research topic. Due to the complexity of the problem, several approaches that exploit FEM analysis have been developed and presented in literature. In this research a 3D thermo-fluid dynamic simulation of an ... Read More

The Analysis of the Conditions of Flow in the Tundish Performed by a Numerical and Physical Method

T. Merder [1], J. Jowsa [2], A. M. Hutny [2], J. Pieprzyca [1], M. Warzecha [2],
[1] Silesian University of Technology, Katowice, Poland
[2] Czestochowa University of Technology, Czestochowa, Poland

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented ... Read More

Numerical Analysis of the Flow Structure in the Continuous Casting Two-strand Tundish

M. Warzecha [1], J. Jowsa [1], A. M. Hutny [1], P. Warzecha [1], T. Merder [2]
[1] Czestochowa University of Technology, Czestochowa, Poland
[2] Silesian University of Technology, Katowice, Poland

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow ... Read More
