Effects of boundary-layer tripping on the acoustic tones of impinging jets
Acta AcusticaThe influence of boundary-layer tripping on the acoustic tones generated by a jet at a Mach number of 0.9 impinging on a flat plate is investigated for two nozzle-to-plate distances.

Advanced Science, EarlyView.A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

Bubbly Jet Impingement in Different Liquids
Microgravity Science and Technology, 2010 An experimental setup for the study of bubbly jets collision in microgravity has been designed. On ground preliminary results are presented in order to be compared with those obtained in a near future in low gravity conditions. The opposed-jet configuration is used with the objective to force the collision of two jets, with an impact angle between them

Challenges and enablers in fluidization technology
AIChE Journal, EarlyView.Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Erosion due to impingement of cavitating jet.
Hydraulics & Pneumatics, 1987 Cavitation erosion produced by impingent of cavitating jet was experimentally studied with specimens of aluminum alloy in high water base fluid of chemical solution type and tap water. Furthermore, the behavior of impinging cavity clouds was observed through instantaneous photographs.
