This article may be used for non-commercial purposes in accordance with the Wiley Self-Archiving Policy  [http://www.wileyauthors.com/self-archiving]. Abstract Large eddy simulation (LES) coupled with Lagrangian particle simulation (LPS) is applied to investigate high-speed turbulent reacting flows. Here, LES solves a velocity field while LPS solves scalar transport equations with notional particles. Although LPS does not require sub-grid scale models for chemical source terms, mole...

Y. Tai, T. Watanabe, K. Nagata Implicit large eddy simulation of passive scalar transfer in compressible planar jet International Journal for Numerical Methods in Fluids, 93 1183-1198 2021 Accepted manuscript is available  here .  This is the accepted version of the article, which has been published in final form at  https://doi.org/10.1002/fld.4924 . This article may be used for non-commercial purposes in accordance with the Wiley Self-Archiving Policy  [http://www.wileyauthors.com/self-archiving]. Abstract Implicit large eddy simulation (ILES) of passive scalar transfer in compressible turbulence is evaluated for subsonic and supersonic turbulent planar jets. The ILES used in this study relies on fully explicit numerical schemes for spatial and temporal discretization and low-pass and shock-capturing filters used as an implicit subgrid-scale (SGS) model. The ILES results are compared with the direct numerical simulation (DNS) database of the same flows. The ILES re...
