Anatomy of a laminar starting thermal plume at high Prandtl number
(2011)We present an experimental study of the dynamics of a plume generated from a small heat source in a high Prandtl number fluid with a strongly temperature-dependent viscosity. The velocity field was determined with particle ... -
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. ... -
The Different Impact of a Half-Separated Gravel and Vegetated Bed in Open Channels
(2015)This paper investigates the different impact of a half-separated gravel and vegetated bed in open channels. This experimental investigation is based on the 2D Particle Image Velocimetry (PIV) method, which allows data ... -
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 ... -
Experimental and Numerical Study of Turbulent Flow in Open Channels with Impermeable and Porous Bed
(2016)In order to experimentally and numerically investigate turbulent flow in an open channel with porous (vegetated) and impermeable bed 2D Particle Image Velocimetry (PIV) and a Computational Fluid Dynamical (CFD) model were ... -
Experimental investigation of the effect of biodiesel blends on a DI diesel engine's injection and combustion
(2017)Differences in the evolution of combustion in a single cylinder, DI (direct injection) diesel engine fuelled by B20 were observed upon processing of the respective indicator diagrams. Aiming to further investigate the ... -
