Noise Generation in the Near-Nozzle Region of a Chevron Nozzle Jet Flow

This paper reports on the simulation of the near-nozzle region of a moderate Reynolds number cold jet flow exhausting from a chevron nozzle. The chevron nozzle considered in this study is the SMC001 nozzle experimentally studied by the researchers at the NASA Glenn Research Center. This nozzle design contains six symmetric chevrons that have a five-degree penetration angle. The flow inside the ...

Flow visualization of the jet exiting a chevron nozzle

Control of jets has been studied for over a century and even today continues to be a significant research topic. It finds applications in various fields especially in aerospace, where enhancement of mixing characteristics of a jet can improve the performance greatly. Review articles by Gutmark et al.;1 Gutmark & Grinstein;2 Seiner et al.;3 Glezer & Amitay;4 Reynolds et al.;5 Ginevsky Vlasov & K...

Simulation Model for Weft Yarn Motion in a Single-Nozzle Air-Jet Loom

Air-jet weaving is an advanced weaving method with high efficiency and productivity. It is one of the most widely used methods of weaving in the world. In air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. After declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by ...
