With the support of the NSERC Discovery Grant "Fundamental Studies on Incompressible Flat-Plate Boundary Layer and Pipe Flow", our group is currently performing investigations on the statistics and coherent structures of zero-pressure-gradient flat-plate boundary layer over a continuous momentum-thickness Reynolds number range from 80 to 3,000. Last year, we reported our DNS on a genuine zero-pressure-gradient flat-plate boundary layer over a low momentum-thickness Reynolds number range from 80 to 1000 (Wu and Moin, JFM, cover-page article of Vol. 630, 2009). The paper has been cited 16 times within the first year after its publication. This work also won the 2008 Gallery of Fluid Motion Competition from the American Physical Society Division of Fluid Dynamics. The comment article written by Professor Marusic (JFM, Vol. 630, 2009) specifically discussing the paper of Wu and Moin has been constantly rated the number-one most downloaded article by JFM-Online since July 2009. A very recent paper by Wu and Moin has once again been selected as the cover-page article on Physics Fluids Vol. 22, no.8, 2010.

在NSERC发现基金“不可压缩平板边界层和管流的基础研究”的支持下，我们的小组目前正在对连续动量-厚度雷诺数范围从80到3，000的零压力梯度平板边界层的统计和相干结构进行研究。 去年，我们报告了我们的DNS在一个真正的零压力梯度平板边界层在低动量厚度雷诺数范围从80到1000（吴和Moin，JFM，封面文章第630卷，2009年）。该论文在发表后的第一年内被引用了16次。这项工作还赢得了2008年画廊的流体运动竞赛从美国物理学会流体动力学分部。Marusic教授撰写的专门讨论Wu和Moin论文的评论文章（JFM，第630卷，2009年）自2009年7月以来一直被JFM在线评为下载量最大的文章。 吴和Moin最近的一篇论文再次被选为2010年第22卷第8期的封面文章。
