Investigation of the Thermal Field on Solid Propellant Grain with Cracks by Moving Particle Semi‐Implicit Method

“…The cracks may be produced on propellant grain in manufacturing process, and Figure 1 shows an X-Ray photography of a propellant grain in the work of Hungler and Petre [21], the pre-existed cracks may affect the combustion efficiency. In this paper, we select a seven-perforated solid propellant grain to analyze the temperature change with different cracks.…”
