Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability. [PDF]
Adv Sci (Weinh)A novel dancing electrospray phenomenon is reported characterized by high‐frequency, robust, and multi‐directional alternating ejection modes. This phenomenon arises from the electrohydrodynamic (EHD) tip streaming at the crests of Faraday waves excited on the liquid meniscus, and it offers significant advantages in high‐throughput and multi‐path ...

Wide-Flow Aerosol Jet Printing Enables High-Throughput, Ultra-Low Aspect Ratio Patterning. [PDF]
Adv Sci (Weinh)Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

Numerical Simulation of Low Reynolds Number Particle-Laden Gas Jet by Vortex Method
Journal of Fluid Science and Technology, 2009 An air jet, which remains laminar and axisymmetric in the single-phase flow condition, is simulated numerically in the particle-laden condition. The vortex method for particle-laden gas jet proposed by the authors is employed for the simulation.
