The direct numerical simulation (DNS) at high Reynolds number of fluid behavior described by the Navier-Stokes equations is particularly costly, if not impossible, since the mesh cells and time step sizes must be adapted to the smallest scales of flu

Dans ce travail, on détermine en premier lieu, la structure dynamique de la dispersion d’un polluant autour d’un obstacle. On montre que la dispersion de polluant est exclusivement tributaire des mouvements turbulents présents, le mécanisme do

In solar power towers, the solar flux is concentrated towards a solar receiver, wherethrough its energy is transferred to a heat transfer fluid. The flow in the solar receiver is turbulent, strongly anisothermal and at low Mach number. The optimisati
