Physics of turbulence and turbulence modelling I

Content

Turbulence decomposition
(mean flow, turbulent stresses, higher-order moments);
second order moments (anisotropy tensor, invariants);
anisotropy invariant mapping of turbulence in wall-bounded flows;
turbulent viscosity, Prandtl-Kolmogorov formula;
dynamics of turbulence dissipation rate;
twopoint correlation technique (locally homogeneous turbulence);
dissipation rate equation (closure model);
velocity-pressure gradient correlations
(Poisson equation, Chou’s integral, slow and fast parts of correlations);
turbulence transport (closure approximation);
predictions (homogeneous shear flows, wall-bounded flows, transitional flows)
