The seventh ERCOFTAC Workshop on "Direct and Large-Eddy Simulation" (DLES-7) was held at the University of Treste from September , Following the tradition of previous workshops in the DLES-series this edition reflects the state of the art of numerical simulation of traditional and turbulent flows and provided an active forum for discussion of recent developments in simulation  › Engineering › Mechanics.   A large eddy simulation of the turbulent syngas non-premixed jet flame of Sandia ETH/Zurich B is conducted using an in-house version of FireFOAM, a fire simulation solver within OpenFOAM. Combustion is modeled using (i) the newly extended eddy dissipation concept for the large eddy simulation published by the authors’ group, (ii) the step CO–H2–O2 mechanism and (iii) the

A Large-Eddy Simulation (LES) is performed for a sooting, lifted, well characterized, non-premixed, turbulent jet flame. In order to accurately predict the lifted flame, a finite-rate chemistry model is used, which requires no assumptions concerning the combustion :// Large-Eddy Simulation of a Shallow Turbulent Jet.
