To improve the operating performance of large-capacity battery pack electric vehicles during continuous charging and discharging to avoid its thermal runaway, in this paper we propose a new hybrid management system that couples PCM with liquid cooling plate microchannels. The flow direction microchannel structure bottom is designed according characteristics large axial conductivity battery, who...

To make an all-electric aircraft possible, both high power densities and efficiencies are needed. However, particularly demands also placed on the thermal management system. Often, electric motor cooling system considered without co-optimization. Particularly in case of motors with conductors directly cooled by a liquid, there is great potential for optimization, since temperature-dependent Jou...

We report dynamic Monte Carlo simulations and statistical thermodynamic theories of a lattice-polymer model, in which polymer crystallization and liquid-liquid demixing of semiflexible homopolymer solutions were investigated simultaneously. In our simulations, the equilibrium phase transition temperature was approached by the onset of phase transitions on cooling, when an introduced substrate g...

Rapid advances in microelectromechanical systems have stimulated the development of compact devices, which require effective cooling technologies (e.g., microchannel cooling). However, the inconsistencies between experimental and classical theoretical predictions for the liquid flow in microchannel remain unclarified. Given the larger surface/volume ratio of microchannel, the surface effects in...

Recently we have shown that Y bInCu4 and related compounds present a solid state Pomeranchuk effect. These systems have a first order volume transition where a local moment phase coexists with a renormalized Fermi liquid in analogy with 3 He at its melting curve. We demonstrate here experimentally that the solid state Pomeranchuk effect, controlled by a magnetic field, can be used to produce co...

integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. a new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. the proposed system includes evacuated tube so...

heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. a heat transfer and solidification model is described for the continuous casting of steel slabs. the model has been established on the basis of the technical conditions of the slab caster in the continuou...

A study was undertaken to investigate the effect of liquid nitrogen aeration on mortalities of adult Cryptolestes furrugineus, rusty grain beetles, in a prototype cardboard grain bin equipped with an aeration system. The grain bin was filled with Hard Red Spring wheat and liquid nitrogen was introduced from the bottom of the bin. The survival of both cold acclimated and unacclimated C. furrugin...

BACKGROUND Polymethylmethacrylate (PMMA) is commonly used for clinical applications. However, the short handling time increases the probability of a surgeon missing the crucial period in which the cement maintains its ideal viscosity for a successful injection. The aim of this article was to illustrate the effects a reduction in temperature would have on the cement handling time during percutan...
