description The goal of this research is to develop a pulse combustion simulation model in order to determine the parameters that influence the pulse combustor’s performance when the design geometry is optimized. The Helmholtz valveless pulse combustor type is one of the simplest pulse combustion processes. It has many advantages over conventional combustion, so it has been employed in a wide range of applications. There are many parameters that need to be studied in order to design this type of combustor to achieve optimal performance. This research presents a numerical and experimental investigation of pulse combustion. Numerical simulations of the pulse combustor’s performance and design parameters are performed using the FLUENT program. These simulations are then experimentally validated and confirmed to be accurately optimized in order to be applicable. The performance of the pulse combustor and NOx emissions were investigated for variable inlet pipe length, tailpipe length, and combustion chamber volumes. This research accurately predicts how the frequency and pressure amplitude change with the variation of the lengths of the inlet pipe and tailpipe, as well as the combustion chamber capacity. The results of this research showed that extremely low NOx emissions were produced by combustion chambers with small volumes and medium tailpipe lengths.
