Data-assisted combustion simulations with dynamic submodel assignment using random forests

no code implementations8 Sep 2020 Wai Tong Chung, Aashwin Ananda Mishra, Nikolaos Perakis, Matthias Ihme

In this investigation, we outline a data-assisted approach that employs random forest classifiers for local and dynamic combustion submodel assignment in turbulent-combustion simulations.
