Importance of the nozzle-exit boundary-layer state in subsonic turbulent jets
To investigate the effects of the nozzle-exit conditions on jet flow and sound fields, large-eddy simulations of an isothermal Mach 0.9 jet issued from a convergent-straight nozzle are performed at a diameter-based Reynolds number of $1\times 10^{6 ...

Evaluation of the efficiency of cleaning dental plaque on titanium using a cavitating jet
Dental plaque, which adheres to the surfaces of dental implants and remains in the gingival crevices, can cause peri-implantitis, which is similar to periodontal disease; consequently, cleaning the dental plaque from these surfaces is very important.

Simulation and experiment of abrasive flow finishing characteristics of nozzle jetting hole runner
When there is a certain inlet chamfer and nozzle taper at the inlet of the nozzle orifice passage, the efficiency of the engine can be further improved by improving the fuel atomization effect of the nozzle.

Nozzle tip wetting in gasoline direct injection injector and its link with nozzle internal flow
Fuel film in the gasoline direct injection injector tip, or so-called nozzle tip wetting, has been found to be an important contributor of particle emissions. Attempts have been made to reduce the nozzle tip wetting by optimizing nozzle geometry designs.

Generation of nanoparticles in the concentrated energy (laser beam) and gas flow
The method of generation and selection of small nanoparticles in the airflow is considered in this paper. To melt the material (stainless steel), a concentrated energy flow – a pulsed solid‐state laser beam – was used.
