Abstract:
In order to meet the engines that can adapt both on the air and in the water. Based on the analysis of improvement and integration of innovative original structure of the chamber, we designed a new air-water chamber. The combustion chamber model in the water and air were constructed by using chamber design theories and formulas of the combustion chamber and the water ramjet combustion engine. Through the improvement of working principle, thermodynamic calculation, 3D design and Numerical simulation, the distribution of the flow field in combustion chamber can be obtained. Moreover, we also analyzed the results of Numerical simulation and pointed out the room for improvement. The finally result proves that the design goal and desired effect is basically achieved.
