The Behaviour of a Turbulent Buoyant Jet into Flowing Environment
(2016)In this study the mean axial velocity at the centreline of a buoyant jet which is discharged vertically upwards from a source, into flowing environment inside a denser ambient fluid (water), in an open channel, is investigated. ... -
Boundary Effects of Vertical Buoyant Jets in a Stagnant Fluid in a Crossflow
(2020)This study includes an experimental study of a buoyant jet in an open channel. For this reason experiments to measure the mean axial velocity at the centreline of a buoyant jet which is discharged vertically upwards from ... -
Effects of different porous beds on turbulent characteristics in an open channel above the porous bed
(2017)An analysis of the turbulent characteristics of the flow in an open channel with horizontal porous beds using two-dimensional (2D) Particle Image Velocimetry (PIV) is presented. Hydraulic characteristics such as velocity ... -
