Modeling Water Immersion Thawing of Raw Tuna Fishes new

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 ...

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

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

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

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

Thermal Design of Power Electronic Devices and Modules

N. Delmonte[1], M. Bernardoni[1], P. Cova[1], and R. Menozzi[1]
[1]Dipartimento di Ingegneria dell’Informazione, University of Parma, Parma, Italy

This work describes a way to apply 3D Finite Element Analysis (FEA) to the thermal design of power electronic modules using simplified geometry models of the system components. The method here presented can overcome the problem of solving equation systems with a very high number of ... Read More

Optimization of Dynamic Embedded, Water Based Surface Heat (and Cold) Emitting System for Buildings
