Ramjet engines have traditionally used liquid fuel which is mixed with atmospheric air and burned to provide thrust for high-speed flight.
传统的冲压喷气发动机使用液体燃料并与大气中的空气混合燃烧，以提供高速飞行的推力。

In order to study the fuel mass flow rate regulation characteristics of tube-in-hole for solid fuelramjet, the flow field of turbulent combustion was numerically analyzed.
During the research on solid fuelramjet (SFRJ), it is an important link for the design and experiment of SFRJ that a suitable mathematical model is built to simulate its internal work process.
