Abstract: The combustion surface regression is studied using Level-set method and minimum distance function (MDF) in SRM. A way that accurately predicts burning surface regression of solid propellant is established based on Level-set method and MDF. The grains with different geometries, the propellant grains with different burning rates and the grains with erosion combustion are calculated and analyzed. The results show that the combined method which calculates the burning area based on interface segmentation and geometric reconstruction has a good adaptability and high reliability on combustion surface regression.
