Abstract

The increasing availability of high-performance computin g resources will allow scale-resolving simulations such as large eddy simulations to be used instead of unsteady Reyno lds-averaged Navier–Stokes approaches, not only in aca- demic research but also for engine combustion process development. The scope of this work is to highlight and dis- cuss this transition to scale-resolving simulations and to propose a systematic approach for model development and application. The current and future scope of industrial and academic research is discussed especially with respect to cycle-to-cycle variations, which canno t be identified with unsteady Reynolds-averaged Navier–Stokes models. The individual processes along the cause-and-effect chain leading to cyclic variations of the combustion process are iden- tified, and the current state of scale-resolving simulati ons and the required models with respect to these processes are discussed.
