DESCRIPTION:Prof. Xiaohua Wu\, Royal Military College of Canada\nBio: B.Sc
 . from the University of Science and Technology of China\; Ph.D from the U
 niversity of Manitoba\, Canada\;\nPost-Doc at CTR (Center for Turbulence R
 esearch)\, Stanford University. Currently Professor and Canada Research Ch
 air at Royal Military College of Canada. Associate Fellow of AIAA.\nAbstra
 ct : Direct numerical simulation of spatially developing pipe flow is perf
 ormed from laminar through transition to fully-developed turbulence.\nThe 
 pipe is 250R long\, and a number of different finite disturbances are impo
 sed at the inlet on either the parabolic or the plug laminar velocity prof
 ile.\nUnder these special inlet disturbances\, isolated Lambda vortices\, 
 hairpin packets\, infant turbulent spot\, mature turbulent spot\,\nand hai
 rpin forest may occur naturally and sequentially. It is also found that en
 ergy norm in the flow downstream of such disturbance\ncan grow exponential
 ly with axial distance
