Characteristic variation of Mach number in subsonic co-flowing jets by varying lip thickness [PDF]
Scientific ReportsJet noise reduction is achieved by jet mixing enhancement which is attributed to potential core length reduction of the primary jet. Varying lip thickness can be considered as a passive control method to reduce the potential core, to enhance mixing. This

Hydrothermal ethanol flames in Co-flow jets [PDF]
The Journal of Supercritical Fluids, 2019 Results on the autoignition and stabilization of ethanol hydrothermal fames in a Supercritical Water Oxidation (SCWO) reactor operating at constant pressure are reported. The flames are observed as luminous reaction zones occurring in supercritical water; i.e., water at conditions above its critical point (approximately 22 MPa and 374 °C).
