Design and simulation of gas burner ejectors
Ignition within gas burner ejectors can lead to off design conditions and has significant influence on the burner behavior. Thus ignition in the ejector should be prevented. In the present study the influence of combustion reactions on the performance of

Ignition characteristics of nitromethane-doped ethanol in a heated shock tube
Ignition delay times of nitromethane-doped ethanol dual fuels are measured under the micro-combustion engine conditions (8 × 105 Pa and 904–1477 K). The promotion effect of nitromethane on ethanol ignition is more pronounced at a fuel-lean condition;

Ignition Delay and Limit of Ignitability for Sodium Pool
Regarding sodium pool burning, ignition delay and ignitability are examined in order to obtain appropriate, comprehensive parameters that can correlate dominant system parameters influencing ignition. To this aim, theoretical work is first conducted, considering that the surface reaction exerts the main influence.
