Characterising entrainment in fountains and negatively buoyant jets
Published 2022Turbulent fountain flow consists of two distinct stages, the initial ‘negatively buoyant jet’ (NBJ) stage, and the fully developed ‘fountain’ stage. The present study investigates both stages of the flow using particle ...Open AccessArticle -
Destratification of thermally stratified turbulent open-channel flow by surface cooling
Published 2020Destratification of thermally stratified open-channel flow by surface cooling is investigated using direct numerical simulation. The initial states are the equilibrium states resulting from radiative heating. Using these ...Open AccessArticle -
Direct numerical simulation and large eddy simulation of wind shear effects on non-stratified open channel flow
Published 2018In this study, direct numerical simulation (DNS) and large eddy simulation (LES) of turbulent channel flow beneath a flat surface with imposed wind shear stress are presented. An open channel with friction Reynolds number ...Open AccessConference paper -
Entrainment across a sheared density interface in a cavity flow
Published 2018The entrainment of fluid across a sheared density interface has been examined experimentally in a purging cavity flow. In this flow, a long straight cavity with sloped entry and exit boundaries is located in the base of a ...Open AccessArticle -
Entrainment and structure of negatively buoyant jets
Published 2021Turbulent negatively buoyant jets occur when the buoyancy of a jet directly opposes its momentum, and will decelerate until its mean momentum is reduced to zero. Here, the flow reverses direction and, for an axisymmetric ...Open AccessArticle -
Evolution of thermally stratified turbulent open channel flow after removal of the heat source
Published 2019Evolution of thermally stratified open channel flow after removal of a volumetric heat source is investigated using direct numerical simulation. The heat source models radiative heating from above and varies with height ...Open AccessArticle -
The influence of sharp meanders on thermally stratified open channel flow
Published 2020In this study, direct numerical simulation (DNS) results for turbulent stratified open channel flow through an idealized meander with an internal heat source that models radiative heating from above are used to investigate ...Open AccessConference paper
