Combustion Chemistry Analysis

Reaction Design’s (www.reactiondesign.com) simulation tools designed to model fuel mixture chemical reactions during the combustion process have been criticized for taking too much time and draining computing resources, so its new CHEMKIN-PRO software package has been designed to operate at faster speeds. “Through a new algorithmic technique we can now take the run time down by a factor up to 20 from where we were just last year,” says Bernie Rosenthal, company CEO, who cites a recent benchmark study of the CHEMKIN-PRO software showing simulation time on a large gas turbine engine dropping to 13 minutes from 5 hours and an ICE engine simulation going to 3 minutes from just under one hour.

The software also includes a particle tracking feature, which models particle growth from inception to oxidation, allowing improved prediction of how nano particles and other materials could impact emission levels. CHEMKIN-PRO can also perform multi-zone modeling to replicate operating conditions in various regions of the cylinder to optimize ignition, flame speed and emission levels.—KMK
