Numerical scheme for simulation of transient flows of non-Newtonian fluids characterised by a non-monotone relation between the symmetric part of the velocity gradient and the Cauchy stress tensor
Adam Janečka, Josef Málek, Vít Průša +1
We propose a numerical scheme for simulation of transient flows of incompressible non-Newtonian fluids characterised by a non-monotone relation between the symmetric part of the ve…

Non-convex dissipation potentials in multiscale non-equilibrium thermodynamics
Adam Janečka, Michal Pavelka
Reformulating constitutive relation in terms of gradient dynamics (being derivative of a dissipation potential) brings additional information on stability, metastability and instab…

Gradient dynamics and entropy production maximization
Adam Janečka, Michal Pavelka
Gradient dynamics describes irreversible evolution by means of a dissipation potential, which leads to several advantageous features like Maxwell--Onsager relations, distinguishing…
