| 1 | 有限负压下熔体硅中磷的挥发去除(英文)显示文摘对有限负压下熔体硅中磷的挥发去除进行研究。采用电子级硅配制Si-P合金,并采用GD-MS来检测实验前后硅中的磷含量。理论计算结果表明:在有限负压下,硅中的磷以P和P2的气体形式从熔体硅中挥发。实验结果显示:在温度1873K、真空度0.6-0.8Pa、熔炼3600s的条件下,熔体硅中的磷从0.046%(460ppmw)下降到0.001%(10ppmw)。实验结果与理论结果一致表明:当熔体硅中磷的含量大且炉腔内气压相对较高时,磷的去除与气压高度相关;而当炉腔气压很低时,磷的去除基本与气压无关。原因是在相对高磷含量的熔体硅中,磷主要以P2气体的形式挥发;在磷含量较低时,磷主要以单原子气体P的形式挥发。 | 郑淞生 Jafar SAFARIAN Seongho SEOK Sungwook KIM Merete TANGSTAD 罗学涛 | 2011 | Transactions of Nonferrous Metals Society of China2011，21，3： | 5 |
| 2 | EMMS drag model for simulating a gas-solid fluidized bed of geldart B particles: Effect of bed model parameters and polydisperity显示文摘The energy minimization multi-scale(EMMS)is a heterogeneous drag model widely used to simulate gas-solid fluidized beds.In this work,we conducted computational fluid dynamics simulations of a gas-solid fluidized bed for Geldart B particles to compare the EMMS with the homogeneous Gidaspow drag model.The results from both the homogeneous and heterogeneous drag models were compared with literature experimental data on pressure drop and bed expansion.There was no noticeable difference in predicted bed characteristics in the slugging regime.However,in the turbulent regime,the EMMS model predicted slightly lower bed expansion than did the Gidaspow model.We evaluated the effects of solid-solid and solid-wall interaction parameters by varying the restitution and specularity coefficients.Bed expansion increases by a factor of 1.05-1.08 when the restitution coefficient increases from 0.9 to 0.99.The models predict a higher solid volume fraction and higher solid downflow velocity near the wall for a low specularity coefficient of 0.01 or 0.When we considered solid phases of different sizes to model polydisperity,the simulation predicted vertical segregation of 300,350,and 400μm in the fluidized region due to gravity.Furthermore,the drag models made similar predictions in bad characteristics from cold model simulation ofa polysilicon fluidized-bed reactor,although there was very little vertical segregation of solid particles for this case. | Krishnadash SKshetrimayum Seongho Park Chonghun Han Chul-Jin Lee | 2020 | Particuology2020，18，4： | 1 |
| 3 | 利用SiO_2-Al_2O_3-CaO-FeO_x四元体系评价煤中矿物质的热及流变特性研究(英文)显示文摘利用SiO_2-Al_2O_3-CaO-FeO_x四元体系研究了煤中矿物质热和黏温特性规律。利用热机械分析、差热、X射线衍射和热力学模拟以及高温旋转黏度计分析了矿物质的高温演化、反应和黏温特性(1700℃到固化温度)。结果表明,热机械分析和差热可以较好地在线考察矿物质高温特性。二氧化硅和氧化铝从低温矿物转变成高温形态,表现出稳定的结构和高黏度;另一方面,加入氧化钙或氧化铁可以起到助熔剂的作用,显著加快二氧化硅和氧化铝的反应和转化并降低黏度。氧化亚铁相比氧化铁和四氧化三铁表现出更明显的降低黏度的作用,而氧化铁还原成金属将显著提高体系黏度。三价铁离子与铝类似,可构成网架结构。另外,氧化铁在弱还原或高温下将产生部分二价铁离子对网架机构进行调整。氧化钙的存在可以加强四元体系中氧化铁的溶解能力,进而降低黏度。 | 王彩红 林雄超 杨萨莎 刘淑琴 YOON Seongho 王永刚 | 2016 | 燃料化学学报2016，44，9： | 1 |
