Nanoscale Heat Transfer and Phonon Hydrodynamics

A. Beardo [1],
[1] Universitat Autònoma de Barcelona, Barcelona, Spain

Several experimental evidences show that macroscopic description of heat transfer phenomena in semiconductors through Fourier law is no longer accurate when the system length and time scales are comparable with the mean free path and relaxation time of the energy carriers (phonons). In ... Per saperne di più

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 ...

Optimum Insulation Thickness Distribution for Heat Loss Uniformity from Heated Corrugated Pipes

R. Bourisli [1],
[1] Kuwait University, Kuwait

Energy loss from fluids flowing across long distances presents a problem in many applications. In the oil and gas industry, for example, crude oil can change in viscosity when modest changes in temperature are realized. This can lead to added pumping power requirement and thus more heat ...
