New paper published that validates a chemical kinetic mechanism for predicting soot formation from advanced biofuels

Thursday, May 28, 2020

Advanced biofuels can reduce emissions of greenhouse gases and particulates from engines; however, computational simulations are necessary to optimize engine design to use these fuels.  These simulations depend on chemical kinetic mechanisms that contain many uncertain rate parameters.  In a new publication in the journal Fuel (https://doi.org/10.1016/j.fuel.2020.118059) we use sooting tendencies we have measured to demonstrate that a mechanism developed at Lawrence Livermore National Laboratory (LLNL) can accurately predict soot formation from 20 advanced biofuels, including alcohols, esters, ketones, furans, and alkenes.  This work was done in collaboration with Yuan Xuan’s group at Penn State and Bill Pitz’ group at LLNL.
