Journal ArticleDOI
A digital filter based generation of inflow data for spatially developing direct numerical or large eddy simulations
TL;DR: In this article, the authors present a new approach for generating artificial velocity data which reproduces first and second order one point statistics as well as a locally given autocorrelation function.
Journal ArticleDOI
Closure of the Transport Equation for the Probability Density Function of Turbulent Scalar Fields
TL;DR: In this article, the transport equation for the probability density function (pdf)P of a scalar variable in a turbulent field is derived and various closure approximations for the turbulent convective and the molecular transport term are discussed.
Journal ArticleDOI
Large Eddy Simulation of Turbulent Combustion Systems
Johannes Janicka,Amsini Sadiki +1 more
TL;DR: A review of recent and ongoing work on numerical models for turbulent combustion systems based on a classical LES approach is presented in this article, where the results show that combustion-LES is able to provide predictions very close to measured data for configurations where the flow is governed by large turbulent structures.
Journal ArticleDOI
Flow field measurements of stable and locally extinguishing hydrocarbon-fuelled jet flames
Journal ArticleDOI
Efficient Generation of Initial- and Inflow-Conditions for Transient Turbulent Flows in Arbitrary Geometries
TL;DR: In this article, a method is presented to generate initial conditions and transient inflow conditions for DNS and LES, which is well suited for the complex geometries and for the arbitrary grids that occur in technical applications.
