Entrainment at the top of the convectively-driven boundary layer (CBL) is revisited using data from a high-resolution large-eddy simulation (LES). In the range of values of the bulk Richardson number RiB studied here (about 15–25), the entrainment

Road traffic is a serious problem in the Chamonix Valley, France: traffic, noise and above all air pollution worry the inhabitants. The big fire in the Mont-Blanc tunnel made it possible, in the framework of the POVA project (POllution in Alpine Vall

Cette étude a concerné la prévalence de l’échinococcose au nord de la Mauritanie. Le taux de prévalence de 37 p. 100, relevé chez les dromadaires originaires de la région de Zoairate, a été significativement plus élevé (p < 0,002) que ce

Mixing depth structure and its evolution have been diagnosed from radar wind profiler data in the Chamonix and the Maurienne valleys (France) during summer 2003. The behaviour of refractive index structure parameter C 2 peaks coupled with the vertica

In optical lithography, the use of multiple focal planes with different energy and focus improves the photolithography performances like the Depth of Focus (DOF) and the Energy Latitude (EL). We have chosen to use a symmetrical double exposure (symme

The exhaust jet of a high-speed aircraft engine expands into a low pressure atmosphere. The gas is a mixture of nitric oxydes NOα with CO2 and air. Three dimensional underexpanded jet with low pressure ratio is computed by large eddy simulation. Hyd

The understanding of turbulent mixing is crucial in the context of chemical reactions. For example the knowledge of quantities like mixing rates are determinant in chemical engineering. Large eddy simulations are very efficient for the calculation of

Coherent structures of turbulent flows are of special interest because of the way they influence flow mixing. Their possibly large length and time scales induce transport of significant amounts of fluid from a location to an other along noticeable di
