Direct numerical simulation of turbulent channel flow up to Re_ = 590.
Direct numerical simulation of turbulent forced convection in a pipe, Int.
Different cases were compared using a direct numerical simulation and the results show that a constant velocity inflow is more unstable than a Poiseuille inflow.
At the eighties, and with the access of data processing to the laboratories of the scientific world, the fashion of the direct numerical simulations settled.
Several typical cases in these two regimes will be examined using direct numerical simulation and will be discussed in this work.
The rise of bubbles in infinite liquid due to the buoyancy force is studied by direct numerical simulation using level set method.
A direct numerical simulation
of laminar and turbulent flow over riblet-mounted surfaces.
Such direct numerical simulations
will permit to give an accurate quantitative description of those systems, that will improve our theoretical understanding and help the analysis of the experiments.
1) understand fundamental properties of stellar dynamos using accurate mean-field models of the direct numerical simulations
The reason is that CFD simulations, except direct numerical simulations
, are always based on models and therefore, inaccuracies are unavoidable.
The direct numerical simulations
will be accompanied with the non-linear stability calculations using the Parabolised Stability Equations (PSE).
On the one hand, by analysing direct numerical simulations
of turbulence the relation between flow topology, local energy dissipation, mixing rates.
