Ignition delay in multifuel mixtures
- 48 Downloads
Methods used to calculate the ignition delay (induction time) of combustible systems consisting of several individual fuels are discussed. A modification of the Arrhenius equation for multifuel mixtures is proposed, which improves the agreement between numerical and experimental data. The method proposed is analyzed by an example of two-fuel systems on the basis of mixtures of carbon oxide with air, the second fuel being hydrogen, acetylene, ethylene, or hexane.
