Scale-resolving Simulations for Combustion Process Development
- 16 Downloads
In the academic community, Large Eddy Simulation is an established research approach while simulations based on Reynolds-Averaged Navier-Stokes equations are mostly used in industry. Since many stochastic engine phenomena such as cycle-to-cycle variations, knock or misfire can only be predicted qualitatively using this approach, there is an increasing interest in the industrial sector in also establishing Large Eddy Simulation. As part of the FVV research project 1215, the Technical University of Darmstadt evaluated the current degree of utilization of the Large Eddy Simulation in the academic and industrial environment.
Scale-resolving Simulations (SRS) are an established research approach at universities for the investigation of non-reactive and reactive flows. In many areas, it has become the de facto standard, replacing Reynolds-averaged Navier-Stokes (RANS) simulations almost entirely. Significant scientific progress has been achieved due to the transition from RANS...
This article is the result of a completed research submission of the Research Association for Combustion Engines e. V. (FVV, Frankfurt am Main, Germany), conducted at the departments of Energy and Power Plant Technology of Technical University of Darmstadt under the direction of Dr.-Ing. Johannes Janicka and Simulation of Reactive Thermo-Fluid Systems of Technical University of Darmstadt under the direction of Dr.-Ing. Christian Hasse. We are grateful to the financial support by FVV under project number 1215. Further thanks are due to Dr.-Ing. Thorsten Unger from Porsche AG for leading the accompanying FVV working group.
