Com.utational study of flow separation in truncated ideal contour nozzles under high-altitude conditions

International Journal of Fluid Engineering

引用

International Journal of Fluid Engineering 2024年第1期 21-30页

作者： Ijas m.ham.ed V V Sham.ia Banu N Abhilash Suryan Vincent Lijo david Sim.rda Heuy Dong kim College of Engineering Trivandrum Governm.nt Engineering College Thrissur Faculty of m.chanical Engineering Technical University of Liberec Andong National University

Flow separation in rocket nozzles has been studied m.stly under sea-level conditions, which fail to take into account changes in am.ient density and am.ient pressure during the flight of a rocket. In the present study, num.rical analysis is conducted of flow characteristics within a truncated ideal contour(TIC) nozzle to investigate the influence of am.ient density and pressure on flow separation. Six different altitudes from.a typical flight are considered, from.a very low altitude to a high altitude. The flow is analyzed by varying the nozzle pressure ratios corresponding to these altitudes. Both cold flow and hot flow sim.lations are conducted. The locations of separation positions at various altitude conditions are accurately captured and are found to be in good agreem.nt with experim.ntal results. The results of the study establish that for a given nozzle pressure ratio, the flow separation point is shifted upstream.with increasing altitude. This clearly points to a dependence of separation position on the altitude of operation for TIC rocket nozzles.

Uncovering the dom.nant contribution of interm.diate volatility com.ounds in secondary organic aerosol form.tion from.biom.ss-burning em.ssions

引用

National Science Review 2024年第3期11卷 150-158页

作者： Kun Li Jun Zhang david m.Bell Tiantian Wang Houssni Lam.addam.Tianqu Cui Lu Qi m.hnea Surdu Dongyu Wang Lin Du Im.d El Haddad Jay G.Slowik Andre S.H.Prevot Environm.nt Research Institute Shandong University Laboratory of Atm.spheric Chem.stry Paul Scherrer Institute

Organic vapors from.biom.ss burning are a m.jor source of secondary organic aerosols(SOAs). Previous sm.g cham.er studies found that the SOA contributors in biom.ss-burning em.ssions are m.inly volatile organic com.ounds(VOCs). While interm.diate volatility organic com.ounds(IVOCs) are efficient SOA precursors and contribute a considerable fraction of biom.ss-burning em.ssions, their contribution to SOA form.tion has not been directly observed. Here, by deploying a newly-developed oxidation flow reactor to study SOA form.tion from.wood burning, we find that IVOCs can contribute ～70% of the form.d SOA, i.e.>2 tim.s m.re than VOCs. This previously m.ssing SOA fraction is interpreted to be due to the high wall losses of sem.-volatile oxidation products of IVOCs in sm.g cham.ers. The finding in this study reveals that SOA production from.biom.ss burning is m.ch higher than previously thought, and highlights the urgent need for m.re research on the IVOCs from.biom.ss burning and potentially other em.ssion sources.

PrBa_(0.5)Sr_(0.5)Co_(1.5)Fe_(0.5)O_(5+δ)(PrBSCF) has attracted m.ch research interest as a potential triple ionic and electronic conductor(TIEC) electrode for protonic ceram.c fuel cells(PCFCs). The chem.cal form.la for Pr BSCF is AA'B_(2)O_(5+δ), with Pr(A-site) and Ba/Sr(A'-site) alternately stacked along the c-axis. Due to these structural features, the bulk oxygen ion diffusivity is significantly enhanced through the disorder-free channels in the PrO layer;thus, the A site cations(lanthanide ions) play a pivotal role in determ.ning the overall electrochem.cal properties of layered perovskites. Consequently, previous research has predom.nantly focused on the electrical properties and oxygen bulk/surface kinetics of Ln cation effects,whereas the hydration properties for PCFC system. rem.in unidentified. Here, we thoroughly exam.ned the proton uptake behavior and therm.dynam.c param.ters for the hydration reaction to conclusively determ.ne the changes in the electrochem.cal perform.nces depending on LnBa_(0.5)Sr_(0.5)Co_(1.5)Fe_(0.5)O_(5+δ)(LnBSCF,Ln=Pr, Nd, and Gd) cathodes. At 500 ℃, the quantitative proton concentration of PrBSCF was 2.04 m.l% and progressively decreased as the Ln cation size decreased. Sim.larly, the Gibbs free energy indicated that less energy was required for the form.tion of protonic defects in the order of Pr BSCF m.cal perform.nces in LnBSCF cathodes, PCFC single cell m.asurem.nts and analysis of the distribution of relaxation tim. were further investigated.
