Computation of plane turbulent flow using probability density function method
Application of the PDF method to turbulence modelling is surveyed. Important parts of the algorithm and of variance reduction techniques used therein are described. The computation results for a free-shear flow (mixing layer) and a wall-bounded flow in simple geometry (channel fiow) are reported and perspectives for further development of the method are suggested.
