is given in the present work to the interaction of twin tandem inclined jets of variable temperature with an oncoming crossflow. This consideration is carried out numerically by means of the finite volume method and is validated by confrontation with experimental data depicted on the same geometric replica by means of the Particle Image Velocimetry (PIV).(More)
A series of numerical simulations are performed to study the pollutant and sediment transport in free surface channel flow. The present paper examines the dispersion of passive contaminants injected from a time periodic source in a fully developed turbulent flow. More precisely, the pulsation effects on the distribution behaviors of dissolved and(More)
—we present in this work a numerical study of pollutant dispersion resulting from a bent chimney around twin obstacles placed in the lee side of the source. A three-dimensional numerical model with the turbulent Reynolds Stress Model (RSM) and a non-uniform grid system was used to examine the effects of a double tandem obstacle cubic on the development of(More)
In order to develop a system of peripheral arterial angioplasty, we carried out an in vitro study to define the quantitative, thermal and morphological characteristics of human-atheroma ablation by excimer laser. A multigas ‘Sopra’ laser was used. The study was performed by using 248nm, krypton fluoride (KrF), then 308nm, xenon chloride (XeCl) wavelengths.(More)
The distribution characteristics of pollutants released at varied rates and different vertical inlet positions of an open channel are investigated via a three-dimensional numerical model. Pollutants are injected from time-dependent sources in a turbulent free-surface flow. Numerical computations were carried out using Fluent 6.3, which is based on the(More)
