Entropic and gradient flow formulations for nonlinear diffusion [PDF]

, 2016
Nonlinear diffusion $\partial_t \rho = \Delta(\Phi(\rho))$ is considered for a class of nonlinearities $\Phi$. It is shown that for suitable choices of $\Phi$, an associated Lyapunov functional can be interpreted as thermodynamics entropy.

Comparative Analysis of Isochoric and Isobaric Adiabatic Compressed Air Energy Storage

Energies, 2023
Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air storage may be isochoric (constant volume) or isobaric (constant pressure).
