Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
Based on Hamilton's principle, the study focuses on a novel strategy for the modeling of non‐Newtonian fluids with the help of internal variables. Here, the viscosity evolves locally in space and time. Three configurations are numerically implemented, namely channel flow, a benchmark, and a lid‐driven cavity.

Error Analysis of a Pressure‐Correction Method With Explicit Time‐Stepping

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We study explicit variants of this well‐established pressure‐correction scheme for solving the Navier–Stokes equations. Step 3 is replaced by an explicit time‐integration method. We give the complete error analysis for this scheme that allows for highly efficient implementations.
