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

200 years of the Navier–Stokes equation
Revista Brasileira de Ensino de FísicaThe year 2022 marked the 200th anniversary of the first appearance of the Navier–Stokes equation, a landmark in Fluid Dynamics introduced by Claude-Louis Navier in 1822.

International Journal for Numerical Methods in Fluids, EarlyView.Compared to experimental data of thermophysical properties of NFs, semi‐empirical models cannot estimate FOM correctly. For all working fluids, applying a converging channel instead of the canonical case was inefficient. Diverging channel was always favored compared to the canonical case. For less effective NFs, both lowering the reference velocity and

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

Accelerating Vortex Particle Methods by Downsampling the Vorticity Field Representation
International Journal for Numerical Methods in Fluids, EarlyView.This paper presents two downsampling algorithms for vortex particle methods (VPMs) that reduce the number of computational elements representing the vorticity field. The two methods demonstrate significant reductions in particle count and computation time in benchmark cases at a cost of diffusive errors.
