    简历：

  • 陈启生：力学所研究员，博士生导师.1989年北京大学力学系流体力学专业毕业，1992年北京大学力学系流体力学专业获硕士学位，1997年在中科院力学所获得博士学位。博士期间工作是关于微重力流体物理研究。1997－2001年在纽约州立大学石溪分校作博士后(Advisor: Prof. V. Prasad)及研究科学家，从事晶体生长模拟工作。2001－2004年在迈阿密佛罗里达国际大学机械工程系担任教师(Faculty Administrator and Coordinator)，讲授机械工程有限元法，并从事氮化物生长模拟工作。2002年作为中科院百人计划回力学所工作，从事微重力流体物理及晶体生长模型化研究。利用数值模拟及三维小扰动线性稳定性理论分析的方法，研究了微重力环境下半浮区液桥的热毛细对流的临界振荡现象，并且确定了液桥体积及细长比对出现振荡对流的临界Marangoni数的影响。从理论上证实了在大Prandtl数情况下，半浮区液桥的热毛细对流的临界振荡Marangoni数对体积曲线有明显的两支。利用流体力学和传热传质的概念，提出了关于碳化硅生长界面的流动-动理学理论模型，即质量输运包括扩散及Stefan对流两种机制,而晶体生长速率与蒸汽的过饱和度成正比。发表SCI收录论文33篇，所发表论文SCI引用280次。
