Additive Manufacturing of NiTi Shape Memory Alloys for Elastocaloric Applications: A Review

open access: yesAdvanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Additive manufacturing enables complex NiTi architectures that overcome key limitations in elastocaloric refrigeration, including poor heat transfer and high mechanical work input. This review surveys recent advances in LPBF‐ and DED‐fabricated NiTi shape memory alloys for elastocaloric applications, highlighting process–structure–performance ...

Nonlocal Internal Variable and Superfluid State in Liquid Helium II

open access: yesMathematics
We present a model of superfluidity based on the internal variable theory. We consider a two-component fluid endowed with a scalar internal variable whose gradient is the counterflow velocity.

Nonlocal and rotational effects in quantum turbulence

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
We discuss phenomenological equations for the evolution of vortex tangle in counterflow superfluid turbulence, which takes into account the influence of the non local effects, both in absence and in the presence of rotation.

Dissipation Triggers Dynamical Two-Stream Instability

open access: yesParticles, 2019
Two coupled, interpenetrating fluids suffer instabilities beyond certain critical counterflows. For ideal fluids, an energetic instability occurs at the point where a sound mode inverts its direction due to the counterflow, while dynamical instabilities ...

Concept of CFD model of natural draft wet-cooling tower flow

open access: yesEPJ Web of Conferences, 2014
The article deals with the development of CFD model of natural draft wet-cooling tower flow. The physical phenomena taking place within a natural draft wet cooling tower are described by the system of conservation law equations along with additional ...
