Math Imitation of the Texture of particle Cluster Emitted from Diesel Engine

摘要

Aim The particle texture from diesel engine was imitated by use of computer. Methods The theory of fractal geometry and the diffusion-limited aggregation model were used to simulate the micron texture. Results The fractal dimensions of granule distribution and corpuscle superficial area are quite conformed with those of measurement. Conclusion The texture parameters of engine particle cluster can be obtained precisely by use of fractal theory.
