AbstractCTS-0081069Paul Durbin, Stanford UniversityBy-pass transition, in which a laminar boundary layer becomes turbulent, without passing through the stages associated with a very low disturbance free stream, is a manifestation of subtle and technologically important physical phenomena. The PI will use sophisticated numerical simulations to execute numerical experiments that will clarify the roles of the competing physical effects in by-pass transition. It is expected that this work will have rather far reaching consequences for aerodynamics and turbomachinary.

斯坦福大学的Paul Durbin：旁路转捩是一种微妙的、技术上重要的物理现象的表现，其中层流边界层在不经过与非常低扰动自由流相关的级的情况下变成湍流。 PI将使用复杂的数值模拟来执行数值实验，以澄清旁路过渡中竞争物理效应的作用。 预计这项工作将对空气动力学和气动学产生相当深远的影响。
