Shear instabilities at low Péclet number
This work addresses stratified shear flows at low Péclet number but high Reynolds number. This little-studied limit is relevant in some astrophysical systems, where the Prandtl number is often very small. Furthermore, it can be studied using a reduced set of ''low-Péclet-number equations''. I will discuss the linear stability and energy-stability properties of spatially periodic flows in this limit, and discuss the results of Direct Numerical Simulations.
