Entropy-stable moving-wall boundary conditions for the ALE formulation of the compressible Navier-Stokes equations
Luca Galimberti, Roberto Nuca, Lisandro Dalcin +2
We present a high-order entropy-stable framework for the compressible Euler and Navier-Stokes equations on moving domains. The space-time mapping describing the domain motion is re…

Entropy conservative and entropy stable solid wall boundary conditions for the resistive magnetohydrodynamic equations
Vladimir Pimanov, Lisandro Dalcin, Matteo Parsani
We present a novel technique for imposing non-linear entropy conservative and entropy stable wall boundary conditions for the resistive magnetohydrodynamic equations in the presenc…

Fully-discrete provably Lyapunov consistent discretizations for convection-diffusion-reaction PDE systems
Rasha Al Jahdali, David C. Del Rey Fernandez, Lisandro Dalcin +1
Convection-diffusion-reaction equations are a class of second-order partial differential equations widely used to model phenomena involving the change of concentration/population o…
