Abstract

To determine more reasonable calculation method for average particle diameter, the differences of internal flow field and performance of solid rocket motor in multi-size and single-size distribution conditions were separately simulated. Numerical simulation using ke turbulence under high Reynolds number and particle trajectory model was introduced. It shows that the results calculated by multi-size distribution are different from that of single size distribution obtained through five calculation methods for average particle diameter. Mass average method and averaging method in volume and surface area are better to calculate particle average diameter, while linear average method should not be used.

Key words： particle trajectory model; mass average method; averaging method in volume and surface area; linear average method
