Combustion Chemical Reaction Analysis Platform
What is Reaction Bench?
Reaction Bench is a simulation platform for combustion chemical reaction analysis based on Cantera. With a GUI interface that requires no programming, it provides an environment for efficiently performing combustion analyses necessary for research and development, from basic analyses such as ignition delay and laminar flow combustion velocity to applied analyses of reciprocating engines.
