“Minimal Composite Equations
 A new way to analyse nonparallel
 Flow instability”
Abstract  

 Shear flow instability is generally addressed using the parallel flow.  Orr-Sommerfeld equation, which is strictly valid only for There are cases (e.g. the classical mixing layer) where this approach leads to qualitatively incorrect results.  The lecture will describe what we have called the `minimal composite equation’ approach (developed with Rama Govindarajan), and the light this  approach can shed on a variety  of shear-flow instability problems.
