摘要
Abstract
To build the test bench for the combustion gas detection of solid propellant,the influence of different pa rameters on gas leak was calculated by computational fluid dynamics (CFD) simulation.The results show that the volume of gas chamber for the test bench should be larger than 2.7 × 105 mm3.The diameter of fan sizing should be Φ100 mm.The influence of gas leak is not obvious when the temperature changes.The sphere and cubic disturbance objects have a significant effect on the three-dimensional model of gas.According to the above simulation results and parameters,the principle diagram of the combustion gas model test bench fo solid propellant was designed.The specific parameters of the test bench were set.The simulated and designed test bench can be used to test the combustion gas by IR-remote detection instrument in next research.关键词
