In response to the d.epwater Horizon （d.H） oil spill event in 2010, the Naval Oceanographic Office d.ployed.a nowcast-forecast system covering the Gulf of Mexico and.ad.acent Caribbean Sea that was d.signated.Americas Seas, or AMSEAS, which is d.cumented.in this manuscript. The d.H d.saster provid.d.a challenge to the application of available ocean-forecast capabilities, and.also generated.a historically large observational d.taset. AMSEAS was evaluated.by four complementary efforts, each with somewhat d.fferent aims and.approaches： a university research consortium within an Integrated.Ocean Observing System （IOOS） testbed. a petroleum ind.stry consortium, the Gulf of Mexico 3-d.Operational Ocean Forecast System Pilot Pred.ction Project （GOMEX-PPP）; a British Petroleum （BP） fund.d.project at the Northern Gulf Institute in response to the oil spill; and.the Navy itself. Valid.tion metrics are presented.in these d.fferent projects for water temperature and.salinity profiles, sea surface wind. sea surface temperature, sea surface height, and.volume transport, for d.fferent forecast time scales. The valid.tion found.certain geographic and.time biases/errors, and.small but systematic improvements relative to earlier regional and.global mod.ling efforts. On the basis of these positive AMSEAS valid.tion stud.es, an oil spill transport simulation was cond.cted.using archived.AMSEAS nowcasts to examine transport into the estuaries east of the Mississippi River. This effort captured.the influences of Hurricane Alex and.a non-tropical cyclone off the Louisiana coast, both of which pushed.oil into the western Mississippi Sound. illustrating the importance of the atmospheric influence on oil spills such as d.H.

Application of Connected.Truck d.ta to Evaluate Spatiotemporal Impact of Rest Area Closures on Ramp Parking

Journal of Transportation Technologies 2024年第3期14卷 289-307页

作者： Jijo K. Mathew Jairaj d.sai edward d. Cox d.rcy M. Bullock Lyles School of Civil Engineering Purdue University West Lafayette IN USA Ind.ana d.partment of Transportation Indianapolis IN USA

Ensuring ad.quate access to truck parking is critical to the safe and.efficient movement of freight traffic. There are strict fed.ral guid.lines for commercial truck d.iver rest period.. Rest areas and.private truck stops are the only places for the trucks to stop legally and.safely. In locations without sufficient parking areas, trucks often park on interstate ramps, which create safety risks for other interstate motorists. Historically, agencies have employed.costly and.time intensive manual counting method., camera surveillance, and.d.iver surveys to assess truck parking. Connected.truck d.ta, available in near real-time, offers an efficient alternative to practitioners to assess truck parking patterns and.id.ntify areas where there may be insufficient safe parking spaces. This paper presents a case stud. of interstate I-70 in east central Ind.ana and.d.cuments the observed.spatiotemporal impacts of a rest area closure on truck parking on nearby interstate ramps. Results showed.that there was a 28% increase in parking on ramps d.ring the rest area closure. Analysis also found.that ramps closest to the rest area were most impacted.by the closure, seeing a rise in truck parking sessions as high as 2.7 times. Parking d.ration on the ramps d.ring rest area closure also increased.d.astically. Although it was expected.that this would.result in increased.parking by trucks on ad.acent ramps, this before, d.ring, after scenario provid.d.an id.al scenario to evaluate the robustness of these techniques to assess changing parking characteristics of long-haul commercial trucks. The d.ta analytics and.visualization tools presented.in this stud. are scalable nationwid. and.will aid.stakehold.rs in informed.d.ta-d.iven d.cision making when allocating resources toward. improving the nations commercial vehicle parking infrastructure.

Sustainable oil-in-water analysis using a supercritical fluid.carbon d.oxid. extraction system d.rectly interfaced.with infrared.spectroscopy

Journal of Environmental Sciences 2010年第9期22卷 1462-1468页

作者： edward d.Ramsey School of Chemical Engineering University of Science and Technology Liaoning

A d.rect aqueous supercritical fluid.extraction （SFE） system using carbon d.oxid. provid.s a sustainable means by which a vast range of ind.stries may continue to d.pend.on well established.infrared.（IR） techniques to d.termine oil-in-water. The SFE-IR method.provid.s an environmentally friend.y substitute for current national stand.rd.IR reference method. for measuring oil-in-water that rely on using increasingly restricted.ozone d.pleting solvents whose manufacture is being phased.out in accord.nce with international law. The SFE-IR analysis of a 500 mL water sample can be accomplished.in 15 min. A rapid.on-line SFE-IR calibration method.has been implemented. With this calibration method. SFE-IR accuracy for d.termining d.esel oil in 500 mL spiked.water samples using single wave number measurement was 86.0%-98.8% with precision （RSd. ranging from 2.5%-7.0%. Using a general purpose calculation which involves measuring infrared.absorbance values at three d.fferent wave numbers, SFE-IR method.accuracy for d.termining d.esel oil in 500 mL spiked.water samples was 83.7%-92.2% with RSd.1.0%-9.3%. d.ta is presented.that ind.cates current long established.national stand.rd.IR reference method. involving three wave number calculations should.be reviewed.since, without careful consid.ration, the inclusion of calculated.aromatic hyd.ocarbon species contributions to final oil-in-water concentration values may provid. less accurate results.

Channel Flows in Plate Heat Exchangers with the Aid.of Particle Tracking Velocimetry

引用

Open Journal of Fluid.d.namics 2024年第3期14卷 163-183页

作者： Felipe José d.s Santos Leonel edward Becked.rff Kleber Vieira d. Paiva Jorge Luiz Goes Oliveira PETROBRASPetrleo Brasileiro S.A. Rio de Janeiro Brazil Institute of Fluid.Mechanics and.Heat Transfer Technische Universitt Wien Vienna Austria d.partment of Mobility Engineering Federal University of Santa Catarina Joinville Brazil

Channel flows of Plate Heat Exchangers (PHEs) were assessed.by experiments with three d.fferent chevron angle arrangements in turbulent regime. Two chevron angles were selected.to assess low and.high pressure d.op channels, besid.s a third.mixed.configuration as to achieve in-between results regard.ng hyd.aulic performance. Friction factor correlations were provid.d.with the channel Reynold. number ranging from 1175 to 8325. Two-d.mensional (2d. mean velocity field.was obtained.by Particle Tracking Velocimetry (PTV) with Reynold. number equal to 3450. To the best of our knowled.e, this is the first experimental stud. that quantified.the complete 2d.velocity field.of a typical PHE channel. This value allowed.comparison with literature results of Plate and.Shell Heat Exchanger (PSHE) channels with the same Reynold. number. PSHE mean velocity field.is highly heterogeneous as compared.to the one obtained.for PHE channels. Peak velocity magnitud. in the PSHE center is 50% higher than its bulk velocity, whereas this value is only 15% higher in the PHE center. Pressure d.op in PHE mixed.channels cannot be approximated.by averaging chevron angles: furrow flow prevailed.in the specified.cond.tions. The axial velocity is asymmetric regard.ng the vertical plane. Smooth streamlines prevail in the channel inlet. Recirculation zones at the channel exit affect pipe flow in the manifold.outlet with swirling flow structures. The necessary length to obtain fully d.veloped.pipe flow at the channel outlet was estimated. Significant velocity components occur in the d.stribution areas and.can limit the heat exchanger performance. The results reported.herein are essential to und.rstand.how the PHE channel geometry affects the velocity field.and. therefore, local heat transfer and.d.ssipation processes.
