Structure-preserving approximation for the non-isothermal Cahn-Hilliard-Navier-Stokes system
Published 31 Jan 2024 in math.NA, cs.NA, and math.AP | (2402.00147v3)
Abstract: In this work we propose and analyse a structure-preserving approximation of the non-isothermal Cahn-Hilliard-Navier-Stokes system using conforming finite elements in space and implicit time discretisation with convex-concave splitting. The system is first reformulated into a variational form which reveal the structure of the equations, which is then used in the subsequent approximation.
