Unconditionally stable, linearised IMEX schemes for incompressible flows with variable density
Nicolás Espinoza-Contreras, Gabriel Barrenechea, Ernesto Castillo +1
For the incompressible Navier--Stokes system with variable density and viscosity, we propose and analyse an IMEX framework treating the convective and diffusive terms semi-implicit…

Implicit-explicit schemes for incompressible flow problems with variable viscosity
Gabriel R. Barrenechea, Ernesto Castillo, Douglas R. Q. Pacheco
In this work we study different Implicit-Explicit (IMEX) schemes for incompressible flow problems with variable viscosity. Unlike most previous work on IMEX schemes, which focuses…
