Mixing at low Reynolds with NEKTAR++

Can hydrodynamic instability be used for mixing? And at the same time can conduits be shaped such that hydraulic losses are reduced? We think that it is Yes to both.

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.

  • Synthetic turbulence generator in Nektar++November 12, 2024
    Advancements in modern hardware and numerical methods have significantly enhanced the feasibility of scale-resolving simulations, such as direct numerical simulation, for industrial applications. For effective application, these simulations require the generation of realistic incoming turbulence to ensure accurate predictions of the flow field.
