May 02, 2015 A numerical investigation of multiple lobed jets was performed using the standard k - ε turbulence model. The present work laid emphasis on understanding the mechanism of mixing enhancement by multiple lobed jets. Further studies were carried out to compare mixing performance of multiple lobed jets with that of multiple conventional round jets for the same

Mar 26, 2010 The flow in the initial region of two jets, namely, a circular orifice jet and a lobed orifice jet, is considered in the present paper. The role played by the Kelvin–Helmholtz (K-H) azimuthal rings and the streamwise vortices in the entrainment process of both jets have been qualitatively and quantitatively analyzed, for a Reynolds number of 3600. This has been

Sep 09, 2013 The mixing mechanisms downstream of an axisymmetric 12-lobed mixer are studied through a combined experimental and computational investigation. A series of simulations based on the unsteady Navier–Stokes equations are used to identify the relative roles of large-scale, instability-driven transient flow structures and smaller-scale turbulence on the flow

May 26, 2021 This study carries out three-dimensional large eddy simulations (LESs) of the flow from a tubular radially lobed nozzle to identify instability mechanisms and vortex dynamics that lead to enhanced mixing. The flow is studied at two Reynolds numbers of around 6000 and 75,000, based on the effective jet diameter.
