Small aircraft propeller noise with ducted propeller [PDF]
4th AIAA/CEAS Aeroacoustics Conference, 1998 The purpose of this paper was to document the results of initial testing of various configurations of a ducted propeller apparatus. The apparatus was designed based on a combination of acoustic principles and a desire to be able to apply the knowledge gained to a practical application such as an ultralight aircraft in an effort to reduce the overall ...

Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Transport of Finite Size Self-Propelled Particles Confined in a 2D Zigzag Channel with Gaussian Colored Noise [PDF]
, 2020 The directional transport of finite size self-propelled Brownian particles confined in a 2D zigzag channel with colored noise is investigated. The noises(noise parallel to x-axis and y-axis), the asymmetry parameter {\Delta}k, the ratio f(ratio of the particle radius and the bottleneck half width), the selfpropelled speed v0 have joint effect on the ...

The European Physical Journal Special Topics, 2016 Self-propelled droplets are a special kind of self-propelled matter that are easily fabricated by standard microfluidic tools and locomote for a certain time without external sources of energy. The typical driving mechanism is a Marangoni flow due to gradients in the interfacial energy on the droplet interface.
