| Research Abstract |
An experiment and numerical simulation were carried out to understand the ultra-high pressure pulse spray characteristics. The spray characteristics such as penetration and dispersion were measured by imaging method which was obtained by high-speed video camera. The unsteady-state two-phase turbulent flow calculation method, k-εmodel and Large Eddy Simulation (LED) are applied to the pulse spray field and a superior results were obtained by using LES. The spray combustion experiment was carried out and a low-NOx combustion was confirmed under certain pulse spray condition.
