Nektar++ and hydrodynamic stability in undulated channels

Nektar++ has been used to study various forms of hydrodynamic instabilities arising is a flow through a channel with corrugated walls. Stability analysis has been performed using direct numerical simulation and tracking growth, or attenuation of the unstable modes.

Dispersion/diffusion analysis and LES
Nektar++ has been recently used to verify the dispersion/diffusion estimates of discontinuous spectral element methods for non-periodic flow problems. This work a key implications on the effective construction of LES tools for industrial problems.
