A thermodynamically consistent Johnson-Segalman-Giesekus model: numerical simulation of the rod climbing effect
Jakub Cach, Patrick E. Farrell, Josef Málek +1
Viscoelastic rate-type fluids represent a popular class of non-Newtonian fluid models due to their ability to describe phenomena such as stress relaxation, non-linear creep, and no…

Stability and error estimates of a linear and partitioned finite element method approximating nonlinear fluid-structure interactions
Bangwei She, Tian Tian, Karel Tuma
We propose and analyze a linear and partitioned finite element method for fluid-shell interactions under the arbitrary Lagrangian-Eulerian (ALE) framework. We adopt the P1-bubble/P…

In vivo evidence of blood flow slippage: failure of the no-slip boundary condition assumption
Alena JarolÃmová, Jaroslav Hron, Karel Tůma +3
The assumption that blood adheres to vessel walls, the ``no-slip'' boundary condition, is an essential premise of cardiovascular fluid dynamics. Yet, whether it holds true \emph{in…
