| 1 | Numerical Analysis on Multi-Field Characteristics and Synergy in a Large-Size Annular Combustion Chamber with Double Swirlers显示文摘In order to comprehensively evaluate the flow and heat transfer performance of a large-size annular combustion chamber of a heavy-duty gas turbine,we carried out numerical computation and analyses on the velocity,temperature and pressure fields in the chamber with double swirlers.The mathematical model of the coupling combustion,gas flow,and heat transfer process was established.The influences of the inlet swirling strength,fuel-air ratio and temperature of the premixed gas on the multi-field characteristics and synergy were investigated on the basis of field synergy theory.The results showed that the central recirculation zone induced by the inlet swirling flow grows downstream in the combustion chamber.The velocity and temperature in the outlet section of the chamber tend to be uniform due to the upstream improved synergy.The outer swirl number of the premixed gas flow has a great influence on the comprehensive flow and heat transfer performance of the combustion chamber.The synergy angles change towards benefiting the synergy between velocity and temperature fields with the increasing swirl numbers and inlet gas temperature while the velocity-pressure synergy becomes poor.The increasing fuel-air ratio of premixed gas leads to different trends of the velocity-temperature synergy and velocity-pressure synergy.The comprehensive synergy representing the low-resistance heat transfer performance is evidently dominated mainly by the velocity-temperature synergy. | Zaiguo Fu Huanhuan Gao Zhuoxiong Zeng Jiang Liu | 2020 | Computer Modeling in Engineering & Sciences2020，，3： | 2 |

| 3 | Research on deepwater synthetic drilling fluid and its low temperature rheological properties显示文摘With the rapid development of deepwater drilling operations,more and more complex technical challenges have to be faced due to the rigorous conditions encountered.One of these challenges is that the drilling fluid used must had good rheological properties at low temperatures and high ability to inhibit hydrate formation.Synthetic drilling fluid has been widely applied to deepwater drilling operations due to its high penetration rate,excellent rheological properties,good ability to prevent hydrate formation,and high biodegradability.A synthetic drilling fluid formulation was developed in our laboratory.The rheological properties of this drilling fluid at low temperatures (0-20 °C) were tested with a 6-speed viscometer and its ability to inhibit hydrate formation was evaluated at 20 MPa CH 4 gas and 0 °C by differential scanning calorimetry (DSC).Several factors influencing the low temperature rheological properties of this synthetic drilling fluid were studied in this paper.These included the viscosity of the base fluid,the amount of CEMU and organic clay,and the water volume fraction. | Hu Youlin Yue Qiansheng Liu Shujie Fu Zaiguo Liang Shan | 2011 | Petroleum Science2011，8，4： | 1 |

| 7 | Comparison of Thermal Performance for Two Types of ETFP System under Various Operation Schemes显示文摘The earth to fluid pipe(ETFP)system has been widely applied to various energy engineering.The numerical model of the heat transfer process in the ETFP system with a shallow-buried horizontal or a deep-buried vertical U-shape pipe adopted in practical engineering was established and the model distinctions were pointed out.The comparison of the thermal performance between the two types of ETFP system under various schemes was conducted on the basis of numerical prediction.The results showed that the thermal parameters of the ETFP system with a shallow-buried horizontal pipe were influenced by the inlet velocity and ground temperature obviously.The variation of the fluid temperature was smooth and the thermal influence zone was limited under the fixed conditions.The proper intermittent operation scheme reduced 53.1%outlet fluid temperature rising.By contrast,the fluid temperature in the ETFP system with a deep-buried vertical U-shape pipe varied dramatically with the operation conditions.The intermittent operation scheme with a relatively short interval led to a less temperature fluctuation of soil around the pipe.The intermittent scheme is beneficial to the recovery of the thermal condition of soil around the U-shape pipe.These results indicated a stark difference in thermal performance between the two types of system.The study can provide guidance for the selection and operation of ETFP system in practical heat exchange engineering. | Lingtong Li Zaiguo Fu Benxiang Li Qunzhi Zhu | 2020 | Computer Modeling in Engineering & Sciences2020，，7： | 1 |

| 13 | 2-21 Attempt to Study the a-decay of 216U by 40Ca+natHf Reaction显示文摘An attempt has been made recently to synthesize very neutron-decient 216U isotope in 40Ca+natHf reaction atthe gas-lled recoil separator SHANS[1]. A beam of 40Ca12+ at an energy of Elab=194.6 MeV was delivered by thesector focusing cyclotron of the Heavy Ion Research Facility in Lanzhou (HIRFL). The average beam intensity wasabout 100 pnA. Self-support targets of natural hafnium foils with thickness of 420 g/cm2 was mounted in a edframe. Evaporation residues recoiled from the target were separated from the primary beam by the separator andthen implanted into the Si-box detector (consist of three position sensitive silicon detectors and eight non-positionsensitive silicon detectors)[2]. In order to distinguish the -decay events from the implantation events, two multi-wire proportional counters (MWPCs) were mounted upstream from the Si-box detector. Behind the Si-box detectora fourfold segmented Clover detector was installed for -ray studies. | Yang Huabin Zhang Zhiyuan Ma Long Yu Lin Jiang Jian Gan Zaiguo Wang Jianguo Tian Yulin Huang Tianheng Wang Yongsheng Sun Mingdao | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |

| 19 | 2-2 Lifetime Measurement of the Low-lying Excited States 7/21^+in^87Zr显示文摘Lifetime measurements of low-lying excited states in^87Zr have been performed viaβ-γcoincidences.The 127 MeV^32S beam was delivered from the Sector-Focusing Cyclotron(SFC)of the Heavy Ion Research Facility in Lanzhou(HIRFL).The parent nuclei^87Nb were produced by the reaction 58Ni(32S,2p1n),at a beam energy 127 MeV through a 8 um Al degrader.A 200ug/cm^2 layer of 58Ni evaporated onto a 200ug/cm^2 thick carbon foil was employed as the target.After evaporation residues were separated from the projectile beams by the gas-filled recoil separator SHANS[1],the nuclei of interest 87Zr can be obtained with a higher purity and then were implanted into a 300um silicon detector. | Qiang Yunhua Liu Minliang Zhou Xiaohong Wang Jianguo Guo Song Wang Kailong Lv Bingfeng Zheng Yong Gan Zaiguo Ma Long Yang Huabin Ding Bing Huang Tianheng Sun Mingdao | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 20 | 2-3 Lifetime Measurement of the First 7/2^+State in 143Eu Based on Gas-flled Spectroscopy显示文摘The application of Lanthanum Bromide(LaBr3)detectors provides a unique opportunity to measure lifetime of excited states in picosecond-nanosecond region.Reducing the background is of critical importance to get precise results.For some excited states feeding from isomers with lifetime longer than 1μs,it can be achieved by the Spectrometer for Heavy Atom and Nuclear Structure(SHANS)[1].143Eu nuclei were populated via the 123Sb(24Mg,4n)fusion-evaporation reaction.Most of the evaporation residues at ground state or long-lived isomers were transferred to detection terminal after a flight of about 1.4μs in SHANS.In the case of 143Eu,three transitions have been observed(Fig.1). | Guo Song Wang Kailong Liu Minliang Zheng Yong Zhou Xiaohong Wang Jianguo Qiang Yunhua Zhang Yuhu Gan Zaiguo Zhang Zhiyuan Ma Long Yang Huabin Yu Lin Ding Bing Jiang Jian Fang Yongde Li Guangshun Zheng Kuankuan | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
