| 2 | 重离子冷却储存环CSRm上的类铍^(40)Ar^(14)+离子的双电子复合和三电子复合显示文摘Electron-ion recombination of Be-like ^(40)Ar^(14)+has been measured by employing the electron-ion merged-beams method at the cooler storage ring CSRm.The measured absolute recombination rate coefficients for collision energies from 0 to 60 eV are presented in Fig.1,covering all dielectronic recombination(DR)resonances associated with 2s^(2)→2s2p core transitions.In addition,strong trielectronic recombination(TR)resonances associated with 2s^(2)→2p^(2) core transitions were observed.Both DR and TR processes lead to series of peaks in the measured recombination spectrum,which have been identified by the Rydberg formula.Theoretical calculations of recombination rate coefficients were performed using the state-of-the-art multi-configuration Breit-Pauli(MCBP)atomic structure code AUTOSTRUCTURE to compare with the experimental results.The plasma rate coefficients for DR+TR of Ar14+were deduced from the measured electron-ion recombination rate coefficients in the temperature range from 10^(3) to 10^(7) K,and compared with calculated data from the literature. | Huang Zhongkui Wen Weiqiang Wang Hanbing Xu Xin Zhu Linfan Wang shuxing Dou Lijun Zhu Xiaolong Yao ke Xu Tianheng Mao Lijun Li Jie Yang Jiancheng Yuan Youjinand Ma Xinwen | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 3 | 3-2 Dielectronic Recombination of Be-like 40Ar14+at the CSRm显示文摘The total recombination rate coefficients of Be-like 40Ar14+ions have been measured by employing the electron-ion merged-beams technique at the heavy ion storage ring CSRm at IMP.Fig.1 shows the recombination spectrum for electron energy from 0 to 58 eV in the center-of-mass frame.The resonant capture,involving the core excitation of an electron and two electrons,which is termed dielectronic recombination(DR)and trielectronic recombination(TR)individually and leads to series of peaks,have been preliminarily identified by extending downward in energy from their series limits with the Rydberg formula[1]. | Huang Zhongkui Wen Weiqiang Wang Hanbing Dou Lijun Zhu Xiaolong Xu Xin Zhu Linfan Wang Shuxing Xu Weiqing Yao ke Xu Tianheng YangYang Mao Lijun Li Jie Yang Jiancheng Yuan Youjin Ma Xinwen | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 4 | 3-6 A Novel Method by Employment of RF-buncher to Study Electron-ion Recombination at Ultra-low Collision Energy at CSRe显示文摘Heavy-ion storage rings equipped with electron coolers have been extensively used for electron-ion recombination studies.For dielectronic recombination(DR)experiments at the CSR,electron cooler is used for cooling of the ion beams as well as for electron target,where electron ion collision energy is detuned by changing the cooler cathode voltage.However,the absolute collision energy close to the cooling point could not be determined precisely in the recent^40Ar^14+DR experiment at the CSRm.Therefore,a novel method by utilizing a RF-buncher instead of the electron cooler to detune collision energy for electron-ion recombination measurement is proposed in this work. | Xu Tianheng Wen Weiqiang Huang Zhongkui Wang Hanbing Dou Lijun Khan Nadir Yao Ke Ma Xinwen | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 5 | Characteristics Analysis of Condensation outside Horizontal Tube Bundles and Novel Condensation Enhancement Method显示文摘Condensation is a phase-change heat-transfer phenomenon crucial in many industries involving latent heat release and mass transfer.Shell-and-tube condensers are essential contributors to the condensation process,and their tube bundles serve as a substrate.Here,the thermal-hydraulic characteristics of condensation in a longitudinal-flow shell-and-tube condenser were investigated numerically.The shell-side longitudinal-flow condensation on the horizontal tube bundles was studied considering inlet flow rate,overheating temperature,and non-condensable gases.Related pressure drops and heat transfer coefficients were subdivided into several components to provide further insights.Two-phase interface behavior analyses were conducted to demonstrate the outcomes with respect to the non-condensable gas layer,vapor quality,and non-condensable gas type.Based on the thorough quantitative analyses outlined above,the thermal resistance of the condensation on the horizontal tube bundle was investigated.The thermal resistance outside the tube was found to dominate the condensation process.Finally,hexagon clamping baffles(HCBs)were introduced as a novel solution to impair condensate boundary layers and provide perturbations to intensify condensation heat transfer.The results revealed that the HCBs enhanced the total heat transfer coefficients by 8.1%–40.7%while reducing the critical overheating temperature and the threshold ratio between sensible and latent heat. | LI Nianqi TIAN Ke KE Hanbing ZENG Min WANG Qiuwang | 2022 | Journal of Thermal Science2022，31，3： | 0 |
