Reseach on the reduction of rocket motor jet noise by water injection
MATEC Web of Conferences, 2016 Injecting water in the mixing layer of rocket motor jets is a means to reduce jet noise. The calculation of the sound pressure signals at the prescribed receivers was performed by FW-H acoustics model under the condition of water injection and without ...

Advanced Materials, EarlyView.We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

Corn plants as temporary acoustic barrier to limit the effects of noise pollution
, 2021 Corn is a cereal imported into Europe from the Americas. It is used for human and animal feed, but there are also industrial uses such as the production of ethanol, of fuel for heating homes, or the production of starch. Corn grows in the summer in areas

Aeroacoustic interactions of installed subsonic round jets
, 2014 Additional noise sources are generated when an aircraft engine is mounted beneath a wing. The two main installation sources include: (1) reflection of the exhaust jet mixing noise from the underside of the wing, and (2) interaction between the turbulent ...
