Notes

The Combustor class models the combustion process in gas turbine engines, splitting the combustor into primary and secondary zones. It uses a Chemical Reactor Network (CRN) approach with Perfectly Stirred Reactors (PSR) and Plug Flow Reactors (PFR) for modeling the combustion process.

Definitions

‘PSR’

Perfectly Stirred Reactor - A reactor model assuming perfect mixing

‘PZ’

Primary Zone - Initial combustion region

‘SZ’

Secondary Zone - Dilution region where the combustion is completed

‘FAR’

Fuel-to-Air Ratio

‘PFR’

Plug Flow Reactor - A reactor model assuming no mixing in axial direction
