Cell-scale hemolysis evaluation of intervenient ventricular assist device based on dissipative particle dynamics

Frontiers in Physiology, 2023
Most of the existing hemolysis mechanism studies are carried out on the macro flow scale. They assume that the erythrocyte membranes with different loads will suffer the same damage, which obviously has limitations.

Electropulsing suppresses extrusion growth in polycrystalline copper subjected to fatigue loading

Mechanical Engineering Journal, 2023
The effect of electropulsing on the extrusion due to persistent slip bands (PSBs) and the defects in PSBs was investigated. To extend the service life and improve structural safety, technology is needed to repair fatigue damage such as cracks and ...

Noise control for high subsonic jet flows by inner wall treatment

Advances in Aerodynamics, 2023
Subsonic jet nozzles, commonly used in passenger aircrafts, generate significant noise that travels both downstream and upstream due to large-scale or fine-scale turbulence in the jet plume.

Advances in the numerical treatment of grain-boundary migration: Coupling with mass transport and mechanics [PDF]

, 2006
This work is based upon a coupled, lattice-based continuum formulation that was previously applied to problems involving strong coupling between mechanics and mass transport; e.g. diffusional creep and electromigration.
