Magneto-Mechanical-Thermal Couplings for the Pulsed Magnetic Technology with Single-Turn Coils

O. Maloberti [1], P. Sansen [1], D. Jouaffre [2], D. Haye [2],
[1] ESIEE Amiens, France
[2] PFT Innovaltech, France

Single turn coils produce AC and transient magnetic fields in pulsed magnetic technologies for which magneto-harmonic and transient magnetic analysis can be primarily performed. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting ... En Savoir Plus

Modeling Water Immersion Thawing of Raw Tuna Fishes

S. Curet [1], O. Rouaud [1], J.M. Bonny [2], L. Mazuel [2],
[1] ONIRIS, CNRS, GEPEA, UMR 6144, Nantes, France
[2] IVIA – IMoST UMR1240 INSERM/UCA, Clermont-Ferrand, France

Thawing processes of raw tuna are widely used as a unit operation dedicated to the canning industry. At the industrial scale, the water immersion process remains the main relevant process for thawing large tuna fishes. The fish is then butchered and the flesh obtained is precooked before ...

Numerical Modeling of Viscous Damping for Acoustic Resonances of Suspended Microparticles

T. Baasch [1], J. Fankhauser [1], J. Dual [1],
[1] ETH Zurich, Zurich, Switzerland

Introduction In this study, we investigate the damping mechanisms of particle resonances in acoustofluidic systems using the finite element framework of COMSOLTM. In the field of acoustic micro-manipulation, pressure waves are used for the contactless handling of micro-meter sized ... En Savoir Plus

疫苗冷链运输箱

豆孟柯 [1], 陈州旗 [1], 刘宝林 [1],
[1] 上海理工大学,上海,中国

一个疫苗冷链运输箱。利用COMSOL Multiphysics 软件的CFD模块对模型进行仿真,利用冷冻至-8℃的冰盒使疫苗冷链运输箱维持在2~8℃。固体冰发生相变,从而产生冰由固体到固液混合再到液体的过程。在这一过程中,可以观察到融化界面、流体域中的速度分布、温度分布。 几何模型:长方体固体冰被塑性材料(简化成薄层)包覆,竖直置于疫苗冷链箱内进行熔融过程。 边界条件:空气域:环境温度Tamb=293.15[K],相变材料:T= 265.15[K],即冰的初始温度; 物理场接口:层流、流体传热 物理模型:1.流体设置中 ... En Savoir Plus

Energy Transformation Damping

G.S. Mulder[1]
[1]Leiden, The Netherlands

A model for material damping is presented in terms of internal friction and in terms of a variation of stiffness. In the latter case the idea is that the stiffness increases if elastic energy is stored and decreases if elastic energy is released. In case of a single mass spring system ... En Savoir Plus
