        abstract = {The pulsejet received a lot of attention during World War II; it operates at subsonic speed, but the technology has never lived up to expectations about performance. Recently, a renewed interest in this technology has led to an upsurge in pulsejet research and experimentation. Recent advancements include attempts to use a pulsejet as a combustor for a gas turbine engine, the use of pulsejets to create greater power, and the ability of pulsejets to function at supersonic speeds.
Reference studies validate that pre-chamber combustion is effective in gasoline IC engines. In this project, a pre-chamber was incorporated into a pulsejet combustor, and combustion analysis was carried out using the CFD simulation software ANSYS Fluent. A pre-chamber is a small chamber typically mounted on top of the main chamber, having a fuel inlet, air inlet, and spark plug. Its volume is 2.4% of the main combustion chamber. Extremely fuel-rich mixture inside the pre-chamber in order to form a low-temperature torch in the form of incomplete combustion products, instead of a flame. On success, the following flame establishment results in pressure increase with an expulsion force that makes partially burnt products ejected out of the pre-chamber into the main chamber, air-fuel in main chamber's is a lean mixture. Combustion efficiency was determined from the mass fractions of fuel species and combustion product species.},
