title = "Dynamic Numerical Simulation of Hybrid Rocket Motors with Fuel Containing Aluminum Hydride",
abstract = "In order to improve the performance of hybrid rocket motors, it is necessary to study high-energy fuels. Hydroxyl terminated polybutadiene fuel added with aluminum hydride is simulated by computational fluid dynamics software in this project. The internal flow field and performance parameters are analyzed. The results show that the port of grain expands with time and a peak appears at the front of the grain. And the peak gradually moves downstream. The main reason is that the vortex appears here and enhances its heat transfer. The simulated data agree well with the experimental data. The error of the pressure between the simulation and the firing test is 1.4\%. And the error of the thrust between the simulation and firing test is 5.3\%. In addition, the regression rate of the simulation is analyzed. The regression rate decreases gradually with time during the working process and the average regression rate is 0.81 mm/s. Furthermore, a regression rate equation is obtained by fitting.",
