EDUCATION 2003.09-2007.07 Dalian University of Technology, undergraduate in Applied Physics; B.S. degree.. 2007.09-2009.03 Dalian University of Technology, postgraduate in Plasma Physics for master degree. thesis title "Numerical simulation of short pulsed discharged using PIC-MCC model", advisor: Prof. Dezhen Wang. 2009.03-2010.08 Dalian University of Technology, postgraduate in Plasma Physics for doctoral degree, advisor: Prof. Dezhen Wang. 2010.09-2011.08 LSPM-CNRS, Université Paris 13, postgraduate (joint-PhD) in Plasma Physics for doctoral degree, advisor: Dr. Xavier Bonnin, the scholarship of China Scholarship Council. 2011.09-2012.07 Dalian University of Technology, postgraduate in Plasma Physics for doctoral degree, thesis title "Modeling of Divertor Plasma Sheath and Hydrogen Isotope Invenroty in Mixed Materials", advisor: Prof. Dezhen Wang. WORK EXPERIENCES 2012.07 - 2014.04 Dalian university of Technology, postdoctor. 2014.04 - 2015.07 Dalian university of Technology, lecturer. 2014.08 - 2016.08 DIII-D National Fusion Facility (USA), General Atomics, Postdoc. 2015.08 - 2017.12 Dalian university of Technology, Associate professor. 2017.12 - present Dalian University of Technology, Professor Research Field 1.Divertor plasma simulation. Develop particle simulation code Edge Plasma Particle-In-Cell (EPPIC1D&2D) to simulate the plasma sheath in the divertor region including divertor gap. The plasma surface interactions (PSI, mainly the erosion processes) have also been investigated. 2.SOL plasma simulation. Simulate the DSOL plasma using Scrape-Off Layer Plasma Simulation (SOLPS) code package. The investigation concentrations are the plasma transport during ELMy H-mode, the divertor in-out asymmetry, and their effects to the divertor target (resulting erosion, fuel retention etc.). 3.Fuel retention inside the plasma-facing wall. To estimate the fuel retention inside the plasma-facing wall (PFW), a rate-theory based code called Hydrogen Isotope Inventory Processes Code (HIIPC1D&2D) has been developed. HIIPC has been applied to simulate the fuel retention in the mixed materials, in the tungsten gap tiles, bubble growth during plasma irradiation and retention during ELMy H-mode etc. RESEARCH PROJECTS (1) Modeling of hydrogen isotope inventory in the tungsten Wall in the tokamaks, China Postdoctoral Science Foundation funded Project No. 2012M520613. (2) Modeling of hydrogen isotope retention in the tungsten divertor of fusion device under different discharge operations, China Postdoctoral Science Foundation funded Project No. 2013T60273. (3) Particle simulation of tokamak scrape-off layer/divertor plasma, the National Natural Science Foundation of China under Grant No. 11305026 (4) National Magnetic Confinement Fusion Science Program No. 2013GB109001.

Research Focus

  • 地球上蕴藏的核聚变能足够使用上百亿年,可控核聚变一旦实现,能源问题则得到彻底解决。磁约束核聚变是最有可能实现的方案,主要装置叫托卡马克。托卡马克中燃料温度将会被加热到上亿度,等离子体是主要存在。此研究方向属于国家重大需求!
    1. 托卡马克边界等离子体物理,是制约装置能够长时间稳态运行的关键问题之一。  
    2.等离子体与器壁相互作用研究,托卡马克中边界等离子体与壁材料直接接触,因此会发生强烈的等离子体与材料相互作用(PSI),从而影响装置的寿命等。
    3.燃料在器壁中的滞留,磁约束核聚变使用的燃料是氘和氚,其中氚是放射性元素,且价格非常昂贵,需要严格限制聚变装置中燃料的滞留量

  • 4. 低温等离子体放电相关
    大气压及低气压放电相关数值模拟研究,在工业具有广泛应用
