Mist Generation Behavior in Ultrasonic Atomizer for Aerosol Jet Printing
James Q Feng, James D Klett, Michael J Renn
Continuous ultrasonic atomization in a closed chamber is expected to generate a mist with an equilibrium droplet concentration and size distribution. Such a mist of microdroplets w…
Mist Flow Visualization for Round Jets in Aerosol Jet Printing
James Q. Feng
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. Th…
A computational study of particle deposition patterns from a circular laminar jet
James Q. Feng
Particle deposition patterns on the plate of inertial impactor with circular laminar jet are investigated numerically with a Lagrangian solver implemented within the framework of t…
A computational study of high-speed microdroplet impact onto a smooth solid surface
James Q. Feng
Numerical solutions of high-speed microdroplet impact onto a smooth solid surface are computed, using the interFoam VoF solver of the OpenFOAM CFD package. Toward the solid surface…
