The Effect of Spanwise Wall Temperature Gradients on Nominally Two-Dimensional Laminar Boundary Layers,

摘要

It is argued that spanwise temperature gradients in wall heating do not affect the boundary layer crossflow to first order if the length scale of the spanwise temperature variation is much greater than the boundary layer thickness. Implications for linear instability theory and transition are discussed for flow about two-dimensional or axisymmetric bodies. (Author)
