Open AccessThe incompressible Navier–Stokes equations form an excellent mathematical model for turbulent flows. However, direct simulations at high Reynolds numbers are not feasible because the convective term produces far too many ...

Open AccessNowadays, turbulent flows are of great interest in many applications because they mix fluid much more effectively than a comparable laminar flow due to its diffusivity. The conservation of the properties of the Navier-Stokes ...
Restricted access - publisher's policyDispersed multiphase turbulent flows are present in many industrial and commercial applications like internal combustion engines, turbofans, dispersion of contaminants, steam turbines, etc. Therefore, there is a clear ...
Study of turbulent natural convection in a tall differentially heated cavity filled with either non-participating, participating grey and participating semigrey media (Université de Poitiers, 2012)
Restricted access - publisher's policyTurbulent natural couvection in a tall differentially heated cavity of aspect ratio 5:1, filled with air under a Rayleigh number based on the height of 4.5.10(10), is studied numerically. Three different situations have ...
