Abstract

The invention discloses a high-enthalpy gas-solid two-phase transverse jet and supersonic airflow coupling generating device and a measuring system. The device comprises a supersonic airflow generator, a pneumatic particle generator, an ethylene / oxygen / air gas generator, and an experimental chamber. Flow field display measurement systems are used to measure the coupling effect of high-enthalpy gas-solid two-phase transverse jet and supersonic airflow in the experimental chamber. The flow field display measurement systems include a filter / photomultiplier tube / ICCD system, a PLIF system, and / ora schlieren system. Various flow field display measurement systems are set on the outside of the experimental chamber. Through the visual window opened on the experimental chamber, the coupling effectof the high-enthalpy gas-solid two-phase transverse jet and supersonic airflow in the experimental chamber is measured, and the measured data is transferred to a computer. The invention can measure the coupling effect of high-enthalpy gas-solid two-phase transverse jet and supersonic airflow.

Description

technical field [0001] The invention relates to the technical field of solid rocket scramjet, in particular to an experimental system for the coupling action of high-enthalpy gas-solid two-phase transverse jet flow and supersonic air flow. Background technique [0002] Solid rocket scramjet is one of the power devices of hypersonic vehicles using solid fuel. In previous solid rocket scramjet experiments, the combustion efficiency of the combustion chamber was relatively low, probably between 50% and 60%. The results of theoretical analysis and numerical simulation show that by setting a suitable turbulence device, the combustion efficiency of the gas phase can reach more than 90%, while the combustion efficiency of solid particles is relatively low. After reviewing domestic and foreign literature, it is found that there are few related achievements, especially those involving the combustion and mixing of solid particles in supersonic airflow. Therefore, it is necessary to ...
