Subgrid combustion modelling for large-eddy simulations:

摘要: AbstractNext-generation gas turbine and internal combustion engines are required to reduce pollutant emissions significantly also be fuel efficient. Accurate prediction of formation requires proper resolution the spatio-temporal evolution unsteady mixing processes. Since conventional steady state methods not able deal with these features, methodology based on large-eddy simulations (LESs) is becoming a viable choice study reacting flows. This paper describes new LES developed recently that has demonstrated capability simulate turbulent flows accurately. A key feature this approach manner in which small-scale processes simulated. allows characterization effects both large-scale convection scalar processes, thereby providing more accurate chemical reaction effects. LESs high Reynolds number pr...
