Combustion of Acetylene and its Performance in Valveless Pulse Jet Engine

Abstract

This paper summarizes the significance of barriers involved in using acetylene as alternate fuel for valve less pulse jet engine. Acetylene gas produces 2210 to 3300 degree Celsius temperatures when allowed to combust with atmospheric air. The idea of high temperature engines is innovatory due to water thermolysis which could accompany the combustion of acetylene. The use of acetylene will reduce emission and increase combustion efficiency. The project investigates the process of combustion of acetylene stoichiometrically with atmospheric air and also with oxygen computationally with the ANSYS Fluent commercial software in a valve less Bailey Machine Services hobby scale pulse jet of 15 centimeter class. The measurement of Pressure, thrust, temperature and concentrations of Carbon monoxide, Nitrous oxide and Hydrocarbons at the exit of pulse jet with acetylene and water thermolysis, Acetylene without water thermolysis and aviation gas without water thermolysis is analyzed and calculated.
