Hybrid RANS/LES of plane impinging jets with k-omega based models [PDF]

open access: yes, 2010
Plane impinging jets with nozzle-plate distances H/B=10 at Re=13500 and H/B=9.2 at Re=20000 are simulated with k-omega based hybrid RANS/LES models. Three ways of substitution of the turbulent length scale by the local grid size in the LES mode of the ...

Mist Flow Visualization for Round Jets in Aerosol Jet Printing

open access: yes, 2018
With the microdroplets of water serving as light scattering particles, the mist flow patterns of round micro-jets can be visualized using the Aerosol Jet(R) direct-write system. The visualization images show that the laminar mist jet appears to extend to
