coupling natural convection heat transfer characteristics of the passive residual heat removal system in AP1000

Zhimin QIU, Daogang LU, Jingpin FU, Li FENG, Yuhao ZHANG

《能源前沿（英文）》 2021年 第15卷 第4期   页码 860-871 doi: 10.1007/s11708-021-0744-1

摘要： Passive residual heat removal heat exchanger (PRHR HX), which is a newly designed equipment in the advanced reactors of AP1000 and CAP1400, plays an important role in critical accidental conditions. The primary and secondary side coupling heat transfer characteristics of the passive residual heat removal system (PRHRS) determine the capacity to remove core decay heat during the accidents. Therefore, it is necessary to investigate the heat transfer characteristics and develop applicable heat transfer formulas for optimized design. In the present paper, an overall scaled-down natural circulation loop of PRHRS in AP1000, which comprises a scaled-down in-containment refueling water storage tank (IRWST) and PRHR HX models and a simulator of the reactor core, is built to simulate the natural circulation process in residual heat removal accidents. A series of experiments are conducted to study thermal-hydraulic behaviors in both sides of the miniaturized PRHR HX which is simulated by 12 symmetric arranged C-shape tubes. For the local PRHR HX heat transfer performance, traditional natural convection correlations for both the horizontal and vertical bundles are compared with the experimental data to validate their applicability for the specific heat transfer condition. Moreover, the revised natural convection heat transfer correlations based on the present experimental data are developed for PRHR HX vertical and lower horizontal bundles. This paper provides essential references for the PRHRS operation and further optimized design.

1000 MW ultra-supercritical turbine steam parameter optimization

FENG Weizhong

《能源前沿（英文）》 2008年 第2卷 第2期   页码 187-193 doi: 10.1007/s11708-008-0030-5

摘要： The 2 × 1000 MW ultra-supercritical steam turbine of Shanghai Waigaoqiao Phase III project, which uses grid frequency regulation and overload control through an overload valve, is manufactured by Shanghai Turbine Company using Siemens technology. Through optimization, the steam pressure is regarded as the criterion between constant pressure and sliding pressure operation. At high circulating water temperature, the turbine overload valve is kept closed when the unit load is lower than 1000 MW while at other circulating water temperatures the turbine can run in sliding pressure operation when the unit load is higher than 1000 MW and the pressure is lower than 27 MPa This increases the unit operation efficiency. The 3D bending technology in the critical piping helps to reduce the project investment and minimize the reheat system pressure drop which improves the unit operation efficiency and safety. By choosing lower circulating water design temperature and by setting the individual Boiler Feedwater Turbine condenser to reduce the exhaust steam flow and the heat load to the main condenser, the unit average back pressure and the terminal temperature difference are minimized. Therefore, the unit heat efficiency is increased.

SHA Yugen, HUANG Songming, ZHANG Aihua, ZHAO Fei, CHEN Ronghua

《医学前沿（英文）》 2008年 第2卷 第1期   页码 35-38 doi: 10.1007/s11684-008-0007-0

摘要： The aim of this paper is to construct a podocin fluorescence expression vector and observe the effects of podocin transfection on CD2AP distribution in HEK293 cells. The pGEMT-easy vector containing the full-length cDNA encoding human podocin was cloned and digested with HI and I. The digested full-length podocin was subcloned into pEGFP-C2. The constructed plasmids were transfected into HEK293 cells and its effects on CD2AP distribution were observed by immunofluorescence. The pEGFP-NPHS2 expression vector was successfully constructed and podocin exclusively located on the HEK293 cell membrane. After podocin transfection, CD2AP redistributed from the perinucleus to the cytoplasm in HEK293 cells. It can be concluded that podocin can recruit CD2AP to redistribute from the perinucleus to the cytoplasm in HEK293 cells.

Aerodynamic stability evolution tendency of suspension bridges with spans from 1000 to 5000 m

《结构与土木工程前沿（英文）》 doi: 10.1007/s11709-023-0980-z

摘要： Aerodynamic instability owing to aerostatic and flutter-related failures is a significant concern in the wind-resistant design of long-span suspension bridges. Based on the dynamic characteristics of suspension bridges with spans ranging from 888 to 1991 m, we proposed fitted equations for increasing spans and base frequencies. Finite element models of suspension bridges with increasing span from 1000 to 5000 m were constructed. The structural parameters were optimized to follow the fitted tendencies. To analyze the aerodynamic instability, streamlined single-box section (SBS), lattice truss section (LTS), narrow slotted section (NSS), and wide slotted section (WSS) were considered. We performed three-dimensional (3-D) full-mode flutter analysis and nonlinear aerostatic instability analysis. The flutter critical wind speed continuously decreases with span growth, showing an unlimited approaching phenomenon. Regarding aerostatic instability, the instability wind speed decreases with span to approximately 3000 m, and increases when the span is in the range of 3000 to 5000 m. Minimum aerostatic instability wind speed with SBS or LTS girder would be lower than observed maximal gust wind speed, indicating the probability of aerostatic instability. This study proposes that suspension bridge with span approximately 3000 m should be focused on both aerostatic instability and flutter, and more aerodynamic configuration optimistic optimizations for flutter are essential for super long-span suspension bridges with spans longer than 3000 m.

《工程（英文）》 2020年 第6卷 第9期   页码 1019-1027 doi: 10.1016/j.eng.2020.02.014

摘要： 这种复合材料由铝（Al）、高氯酸铵（ammonium perchlorate, AP）和聚偏氟乙烯（polyvinylidene fluoride, PVDF）组成，其中Al作为燃料，AP和PVDF共同作为氧化剂，并根据最大反应放热量确定AP和PVDF的添加比例。氧化石墨烯的加入提高了Al@AP/PVDF的反应速率并改善了其热稳定性。掺杂0.2%氧化石墨烯的Al@AP/PVDF使得火焰传播速率达到了4.76 m·s–1，相对于Al@AP/PVDF的火焰传播速率提高了约10.7%。掺杂氧化石墨烯的Al@AP/PVDF（Al@AP/PVDF-GO）具有更好的界面接触和颗粒分散性，从而提高了传热速率，消除了纳米铝（nano-Al）粉微粒的团聚现象，提高了燃烧反应速率。

Energy supply for water electrolysis systems using wind and solar energy to produce hydrogen: a case study of Iran

Mostafa REZAEI, Ali MOSTAFAEIPOUR, Mojtaba QOLIPOUR, Mozhgan MOMENI

《能源前沿（英文）》 2019年 第13卷 第3期   页码 539-550 doi: 10.1007/s11708-019-0635-x

摘要： Due to acute problems caused by fossil fuels that threaten the environment, conducting research on other types of energy carriers that are clean and renewable is of great importance. Since in the past few years hydrogen has been introduced as the future fuel, the aim of this study is to evaluate wind and solar energy potentials in prone areas of Iran by the Weibull distribution function (WDF) and the Angstrom-Prescott (AP) equation for hydrogen production. To this end, the meteorological data of solar radiation and wind speed recorded at 10 m height in the time interval of 3 h in a five-year period have been used. The findings indicate that Manjil and Zahedan with yearly wind and solar energy densities of 6004 (kWh/m ) and 2247 (kWh/m ), respectively, have the greatest amount of energy among the other cities. After examining three different types of commercial wind turbines and photovoltaic (PV) systems, it becomes clear that by utilizing one set of Gamesa G47 turbine, 91 kg/d of hydrogen, which provides energy for 91 car/week, can be produced in Manjil and will save about 1347 L of gasoline in the week. Besides, by installing one thousand sets of X21-345 PV systems in Zahedan, 20 kg/d of hydrogen, enough for 20 cars per week, can be generated and 296 L of gasoline can be saved. Finally, the RETScreen software is used to calculate the annual CO emission reduction after replacing gasoline with the produced hydrogen.
