Notes

This class implements properties for butanol fuel, including options forboth simplified and detailed chemical kinetics. Properties are specified at standard conditions (15°C, 1 atm).

Definitions

‘Lower Heating Value’

Heat of combustion excluding latent heat of water vapor

‘Global Warming Potential’

Relative measure of heat trapped in atmosphere compared to CO2

Major Assumptions

  • Properties are for standard temperature and pressure conditions (20C, 1atm)
