MULTI-SCALE MODELING AND ANALYSIS OF CONVECTIVE BOILING: TOWARDS THE PREDICTION OF CHF IN ROD BUNDLES

B. NICENO,Y. SATO,A. BADILLO,M. ANDREANI 한국원자력학회 2010 Nuclear Engineering and Technology Vol.42 No.6

In this paper we describe current activities on the project Multi-Scale Modeling and Analysis of convective boiling (MSMA),conducted jointly by the Paul Scherrer Institute (PSI) and the Swiss Nuclear Utilities (Swissnuclear). The long-term aim ofthe MSMA project is to formulate improved closure laws for Computational Fluid Dynamics (CFD) simulations for predictionofconvective boiling and eventually of the Critical Heat Flux (CHF). As boiling is controlled by the competitionof numerousphenomena at various length and time scales, a multi-scale approach is employed to tackle the problem at different scales. Inthe MSMA project, the scales on which we focus range from the CFD scale (macro-scale), bubble size scale (meso-scale),liquid micro-layer and triple interline scale (micro-scale), and molecular scale (nano-scale). The current focus of the projectis on micro- and meso- scales modeling. The numerical framework comprises a highly efficient, parallel DNS solver, thePSI-BOIL code. The code has incorporated an Immersed Boundary Method (IBM) to tackle complex geometries. For simulationof meso-scales (bubbles), we use the Constrained Interpolation Profile method: Conservative Semi-Lagrangian 2ndorder(CIP-CSL2). The phase change is described either by applying conventional jump conditions at the interface, or by using thePhase Field (PF) approach. In this work, we present selected results for flows in complex geometry using the IBM, selectedbubbly flow simulations using the CIP-CSL2 method and results for phase change using the PF approach. In the subsequentstage of the project, the importance of effects of nano-scale processes on the global boiling heat transfer will be evaluated.To validate the models, more experimental information will be needed in the future, so it is expected that the MSMA projectwill become the seed for a long-term, combined theoretical and experimental program.

Critical illness can be associated with transient alterations in circulating thyroid hormone concentrations, indicating the presence of non-thyroidal illness (NTI). NTI is well described in humans, but there are few reports on its occurrence and prognostic significance in dogs. This retrospective study assessed the occurrence of NTI in a population of dogs with systemic inflammatory response syndrome (SIRS) and investigated its association with disease severity (APPLEfast scores). A total of 41 SIRS dogs were included and were divided by SIRS origin (non-septic SIRS, n = 10; septic SIRS, n = 41) and final outcome (survivors, n = 37; non-survivors, n = 4). Healthy, age-matched dogs (n = 15) were included as controls. Serum thyroid hormone levels including total T3, free T3, total T4, and reverse T3 were measured upon admission. Compared to controls, there were significant changes in serum thyroid hormone concentrations in SIRS dogs, suggesting the presence of NTI. Septic SIRS dogs had higher APPLEfast scores and lower serum thyroid hormones concentrations than those in non-septic SIRS and control dogs. In conclusion, NTI was frequent in dogs with SIRS and may be associated with the presence of sepsis or high illness severity.

THE 2014 ALMA LONG BASELINE CAMPAIGN: OBSERVATIONS OF THE STRONGLY LENSED SUBMILLIMETER GALAXY HATLAS J090311.6+003906 AT <i>z</i> = 3.042

Vlahakis, C.,Hunter, T. R.,Hodge, J. A.,Pé,rez, L. M.,Andreani, P.,Brogan, C. L.,Cox, P.,Martin, S.,Zwaan, M.,Matsushita, S.,Dent, W. R. F.,Impellizzeri, C. M. V.,Fomalont, E. B.,Asaki, Y.,Barka IOP Publishing 2015 ASTROPHYSICAL JOURNAL LETTERS - Vol.808 No.1

<P>We present initial results of very high resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the z = 3.042 gravitationally lensed submillimeter galaxy HATLAS J090311.6+003906 (SDP. 81). These observations were carried out using a very extended configuration as part of Science Verification for the 2014 ALMA Long Baseline Campaign, with baselines of up to similar to 15 km. We present continuum imaging at 151, 236, and 290 GHz at unprecedented angular resolutions as fine as 23 mas, corresponding to an unmagnified spatial scale of similar to 180 pc at z = 3.042. The ALMA images clearly show two main gravitational arc components of an Einstein ring, with emission tracing a radius of similar to 1 ''.5. We also present imaging of CO J = 10 - 9, J = 8 - 7, and J = 5 - 4 and H2O (202-111) line emission. The CO emission, at an angular resolution of similar to 170 mas, is found to broadly trace the gravitational arc structures but with differing morphologies between the CO transitions and compared to the dust continuum. Our detection of H2O line emission, using only the shortest baselines, provides the most resolved detection to date of thermal H2O emission in an extragalactic source. The ALMA continuum and spectral line fluxes are consistent with previous Plateau de Bure Interferometer and Submillimeter Array observations despite the impressive increase in angular resolution. Finally, we detect weak unresolved continuum emission from a position that is spatially coincident with the center of the lens, with a spectral index that is consistent with emission from the core of the foreground lensing galaxy.</P>

Evolution of dust temperature of galaxies through cosmic time as seen by <i>Herschel</i>^★

<P>ABSTRACT</P><P>We study the dust properties of galaxies in the redshift range 0.1 ≲<I>z</I>≲ 2.8 observed by the <I>Herschel Space Observatory</I> in the field of the Great Observatories Origins Deep Survey-North as part of the PACS Extragalactic Probe (PEP) and <I>Herschel</I> Multi-tiered Extragalactic Survey (HerMES) key programmes. Infrared (IR) luminosity (<I>L</I><SUB>IR</SUB>) and dust temperature (<I>T</I><SUB>dust</SUB>) of galaxies are derived from the spectral energy distribution fit of the far-IR (FIR) flux densities obtained with the PACS and SPIRE instruments onboard <I>Herschel</I>. As a reference sample, we also obtain IR luminosities and dust temperatures of local galaxies at <I>z</I> < 0.1 using <I>AKARI</I> and <I>IRAS</I> data in the field of the Sloan Digital Sky Survey. We compare the <I>L</I><SUB>IR</SUB>–<I>T</I><SUB>dust</SUB> relation between the two samples and find that the median <I>T</I><SUB>dust</SUB> of <I>Herschel</I>-selected galaxies at <I>z</I>≳ 0.5 with <I>L</I><SUB>IR</SUB>≳ 5 × 10<SUP>10</SUP> L<SUB>⊙</SUB> appears to be 2–5 K colder than that of <I>AKARI</I>-selected local galaxies with similar luminosities, and the dispersion in <I>T</I><SUB>dust</SUB> for high-<I>z</I> galaxies increases with <I>L</I><SUB>IR</SUB> due to the existence of cold galaxies that are not seen among local galaxies. We show that this large dispersion of the <I>L</I><SUB>IR</SUB>−<I>T</I><SUB>dust</SUB> relation can bridge the gap between local star-forming galaxies and high-<I>z</I> submillimetre galaxies (SMGs). We also find that three SMGs with very low <I>T</I><SUB>dust</SUB> (≲20 K) covered in this study have close neighbouring sources with similar 24-μm brightness, which could lead to an overestimation of FIR/(sub)millimetre fluxes of the SMGs.</P>
