摘要:... In the first approach, the non-linear model of Ehrhard and Moussiopoulos was employed as one of the best cubic non-linear eddy viscosity models, and large eddy simulation was utilized in the second approach. The obtained results suggest that although the non-linear model has ...

摘要:Abstract(#br)A study on the coal particle history during combustion in a large-scale furnace using large eddy simulation is presented. The massively parallel execution produces a high-resolution representation of the fluid mixing and particle dispersion throughout the whole compu...

摘要:Abstract(#br)This study presents an alternative way to perform large eddy simulation based on a targeted numerical dissipation introduced by the discretization of the viscous term. It is shown that this regularisation technique is equivalent to the use of spectral vanishing visco...

摘要:Abstract(#br)Large eddy simulation (LES) is used to predict the turbulent flow structures and film-cooling characteristics of the unsteady jet/cross-flow interactions in a fan-shaped hole. The coolant hole is located on a flat plate surface with a 35 degree angle with respect to ...

摘要:Abstract(#br)In this paper, we apply a specifically designed dissipative spatial filter as sub-grid scale model within the increasingly popular discontinuous Galerkin methods and the closely related flux reconstruction high order methods for large eddy simulation. The parameters ...

摘要:Abstract(#br)This work investigated the chemical kinetics processes of diesel combustion under compression ignition combustion conditions using the large eddy simulation approach. An overall reasonable agreement with the experimental combustion results was obtained. To further in...

摘要:Abstract(#br)The accuracy, efficiency and scalability of explicit and implicit temporal schemes associated with FR/CPR spatial schemes are studied in the context of large eddy simulation. One low pressure turbine and one high pressure turbine blade cases with different Mach n...

摘要:... This article presents the numerical results of two thermal turbulent mixing simulations, applied to a T-junction (OECD-NEA-Vattenfall T-junction). These simulations apply, respectively, to the case of a flow with and without rotational movements into the cold side. The numeri...

摘要:Abstract(#br)The Large Eddy Simulation model was introduced to study the micro spray characteristics under ultra-high injection pressure (>220MPa). EFS8400 spray test platform was set up to verify the accuracy of the numerical model. The mechanisms of micro spray characteristics ...

摘要:... As the affordability and availability of computing power has increased, these codes have found themselves pushed into service as large eddy simulation solvers. The approximate Riemann solver of Roe, which is frequently used as the core method in such legacy codes, is shown t...
