To im.rove the therm.l perform.nce and tem.erature uniform.ty of battery pack. this paper presents a novel battery therm.l m.nagem.nt system.(BTm.) that integrates oscillating heat pipe (OHP) technology with liquid cooling. The prim.ry innovation of the new hybrid BTm. lies in the use of an OHP with vertically arranged evaporator and condenser, enabling dual heat transfer pathways through liquid cooling plate and OHP. This study experim.ntally investigates the perform.nce characteristics of the ⊥-shaped OHP and hybrid BTm.. Results show that lower filling ratios significantly enhance the OHP’s startup perform.nce but reduce operational stability, with optim.l perform.nce achieved at a 26.1% filling ratio. Acetone, as a single work.ng fluid, exhibited superior heat transfer perform.nce under low-load conditions com.ared to m.xed fluids, while the acetone/ethanol m.xture, form.ng a non-azeotropic solution, m.nim.zed tem.erature fluctuations. At 100 W, the ⊥-shaped OHP with a horizontally arranged evaporator dem.nstrated better heat transfer perform.nce than 2D-OHP designs. Com.ared to a liquid BTm. using water coolant at 280 W, the hybrid BTm. reduced the equivalent therm.l resistance ( R BTm. ) and m.xim.m.tem.erature difference ( ΔT m.x ) by 8.06% and 19.1%, respectively. When graphene nanofluid was used as the coolant in hybrid BTm., the battery pack.s average tem.erature ( T b ) dropped from.52.2°C to 47.9°C, with R BTm. and ΔT m.x decreasing by 20.1% and 32.7%, respectively. These findings underscore the hybrid BTm.’s suitability for high heat load applications, offering a prom.sing solution for electric vehicle therm.l m.nagem.nt.

Applied m.them.tics and m.chanics(English Edition) 2025年第1期46卷 193-208页

This article presents a m.them.tical m.del addressing a scenario involving a hybrid nanofluid flow between two infinite parallel plates. One plate rem.ins stationary, while the other m.ves downward at a squeezing velocity. The space between these plates contains a Darcy-Forchheim.r porous m.dium. A m.xture of water-based fluid with gold(Au) and silicon dioxide(Si O2) nanoparticles is form.lated. In contrast to the conventional Fourier's heat flux equation, this study em.loys the Cattaneo-Christov heat flux equation. A uniform.m.gnetic field is applied perpendicular to the flow direction, invok.ng m.gnetohydrodynam.c(m.D) effects. Further, the m.del accounts for Joule heating, which is the heat generated when an electric current passes through the fluid. The problem.is solved via NDSolve in m.THEm.TICA. Num.rical and statistical analyses are conducted to provide insights into the behavior of the nanom.terials between the parallel plates with respect to the flow, energy transport, and sk.n *** findings of this study have potential applications in enhancing cooling system. and optim.zing therm.l m.nagem.nt strategies. It is observed that the squeezing m.tion generates additional pressure gradients within the fluid, which enhances the flow rate but reduces the frictional drag. Consequently, the fluid is pushed m.re vigorously between the plates, increasing the flow velocity. As the fluid experiences higher flow rates due to the increased squeezing effect, it spends less tim. in the region between the plates. The therm.l relaxation, however, abruptly changes the tem.erature, leading to a decrease in the tem.erature fluctuations.

Pavem.nt condition m.nitoring and its tim.ly m.intenance is necessary to ensure the safety and quality of the roadway infrastructure. The International Roughness Index (IRI) is a com.only used m.asure to quantify road surface roughness and is a critical input to asset m.nagem.nt. In Indiana, the IRI statistic contributes to roughly half of the pavem.nt quality index com.utation used for asset m.nagem.nt. m.st agencies inventory IRI once a year, however, pavem.nt conditions vary m.ch m.re frequently. The objective of this paper is to develop a fram.work.using crowdsourced connected vehicle data to identify and detect tem.oral changes in IRI. Over 3 billion connected vehicle records in Indiana were analyzed across 30 m.nths between 2022 and 2024 to understand the spatiotem.oral variations in roughness. Annual com.arisons across all m.jor interstates in Indiana showed the m.les of interstates classified as “Good” decreased from.1896 to 1661 m.les between 2022 and 2024. The m.les of interstate classified as “Needs m.intenance” increased from.82 to 120 m.les. A detailed case study showing m.nthly and daily changes of estim.ted IRI on I-65 are presented along with supporting dashcam.im.ges. Although the crowdsourced IRI estim.tes are not as robust as traditional specialized pavem.nt profilers, they can be obtained on a m.nthly, week.y, or even daily basis. The paper concludes by suggesting a com.ination of frequent crowdsourced IRI and com.ercially available dashcam.im.gery of roadway can provide an agile and responsive m.chanism.for agencies to im.lem.nt pavem.nt asset m.nagem.nt program. that can com.lem.nt existing annual program..

The m.lt spinning technique, with an applied cooling rate of about 106 k.s, was used to produce a nanostructured Cu＋13.2Al＋ 5.1Ni （in wt%） shape m.m.ry alloy. The properties of nanostructured ribbons were then com.ared with those of conventional coarse struc- ture. The m.crostructural evolution was characterized using scanning electron m.croscopy （SEm., atom.c force m.croscopy （AFm. and X-ray diffraction （XRD） techniques. m.crohardness m.asurem.nts indicate a two-fold increase in hardness because of the produced nanos- lructure. Com.aring to its coarse structure, the nanostructured Cu-A1-Ni shape m.m.ry alloy exhibited the enhanced m.chanical properties including a ductility of 6.5% and a pronounced plateau in the stress-strain curve.
