Abstract:
Based on Fluent software,numerical investigation is performed on working process, including non-reacting flow before ignition and two phases reacting flow after ignition,in a liquid ramjet combustion chamber.The inner flow characteristics of two different block-area—ratio schemes ale analyzed in total pressure loss and recirculation region distribution.After comparison,the smaller block—area-ratio scheme with good performance is chosen.Then simulation of two phases reacting flow is performed,and temperature field,fuel distribution and combustion efficiency are obtained, which helps to decide a reasonable fuel feeding scheme.At last,the results of three dimensional simulation provide a more particular understanding of flow and combustion process,and simulation results fit the experiment data well.
