Weekly Seminar: Spring 2013

Speaker: Dr. Xiaohua Wu (Royal Military College of Canada)
Title: "Osborne Reynolds Pipe Flow and Ludwig Prandtl Boundary Layer: Direct Computation from Laminar to Fully-Developed Turbulence"

Date: Friday, February 1, 2013
Time: 11:00 a.m.
Location: Gilman Hall 50 (Marjorie M. Fisher Hall)


Abstract

Modern fluid mechanical science rests upon two corner-stone building blocks: the incompressible flow through a smooth pipe (the Osborne Reynolds pipe flow), and the incompressible boundary layer over a smooth flat-plate at zero pressure-gradient (the Ludwig Prandtl boundary layer). These two idealizations, in the meantime, are also the limiting cases and calibration benchmarks of many complicated practical engineering flows. Recently, we computed the pipe flow and the boundary layer from first-principle in the laboratory framework. The pipe flow exhibits a turbulence onset scenario that bears certain similarities and differences to the bypass transition process found in the boundary layer with continuous free-stream turbulence.

Bio

Dr. Wu is an Associate Professor in the Department of Mechanical and Aerospace Engineering at the Royal Military College of Canada. He currently holds the Tier-2 Canada Research Chair in Aeronautical Fluid Mechanics. Prior to joining the Royal Military College, he did his post-doctoral research work at Stanford University, Arizona State University and the University of Vermont.
