Abstract :
An analysis of the ignition delay time dependence on microwave energy input time, electric field strength, and discharge energy at high-pressure conditions is presented for a combined laser-microwave ignition. The existence of a saturation power effect at high-pressure conditions is predicted. An analytical formula for a laminar flame velocity is obtained for a case of the reaction rate dependence on vibrational temperature.
