WAVE PROPAGATION ANALYSIS IN A PRESSURE-WAVE-REFRIGERATOR [PDF]

open access: yesModern Physics Letters B, 2005
Pressure wave refrigerators (PWR) refrigerate the gas through periodical expansion waves. Due to its simple structure and robustness, PWR may have many potential applications if the efficiency becomes competitive with existing alternative devices.

Spatio-Temporal Plasma Afterglow Induces Additional Neutral Drag Force on Microparticles

open access: yesFrontiers in Physics, 2022
An emerging topic in complex plasma physics is the interaction between dust particles and afterglow plasmas. Control of plasma-particle interactions and specifically of the particle trajectories is especially relevant for plasma based contamination ...

Numerical simulation of cavitation-bubble expansion and collapse inside a bottle subjected to impact on its topside

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
In this study, we simulate the acceleration-induced cavity bubble expansion and its non-spherical collapse in a drastically varying pressure field caused by mechanical impact, and we qualitatively compare the results with those for similar ζ number ...
