ORCh background

ORCh (Optimised and Reduced Chemistry) is a fully automated method to reduce detailed chemical schemes. This page describes the architecture of the method and explains how to install and run ORCh.

ORCh is reported in two archival papers (make sure to cite those papers when using this program):

• N. Jaouen, L. Vervisch, P. Domingo (submitted) Auto-thermal reforming (ATR) of natural gas: An automated derivation of optimised reduced chemical schemes.
• N. Jaouen, L. Vervisch, P. Domingo, G. Ribert (submitted) Automatic reduction and optimisation of chemistry for turbulent combustion modelling: Impact of the canonical problem
