Large eddy simulation (LES) is computationally extremely expensive for the investigation of wall-bounded turbulent flows at high Reynolds numbers. A way to reduce the computational cost of LES by orders of magnitude is to combine LES equations with R

A transported probability density function (PDF) method developed for pulverized coal combustion is applied in simulations of a semi-industrial scale furnace. It is found that the simulation results are sensitive to the chosen model for unclosed term

A transported probability density function (PDF) method is developed for pulverized coal combustion. Two separate PDF transport equations, one for the gas phase (joint velocity-composition PDF) and one for the coal particle phase, are solved by means

Numerical simulation results obtained with a transported scalar probability density function (PDF) method are presented for a piloted turbulent premixed flame. The accuracy of the PDF method depends on the scalar mixing model and the scalar time scal

characteristic length and time scales of inflowing turbulent eddies are consistent with the corresponding Reynoldsaveraged Navier–Stokes profiles imposed at the inlet. The resulting large-eddy simulation method is validated against experimental dat

The accurate and efficient simulation of both attached and separated flows represents a huge challenge. RANS methods suffer from the lack of ability to simulate instantaneous turbulence structures, and LES methods are computationally very expensive r

The use of probability density function (PDF) methods for turbulent combustion simulations is very attractive because arbitrary finite-rate chemistry can be exactly taken into account. PDF methods are well developed for non-premixed turbulent combust

The use of probability density function (PDF) methods for turbulent combustion simulations is very attractive because arbitrary finite-rate chemistry can be exactly taken into account. However, many real flames involve a variety of mixing regimes (no
