基于分形布朗运动的烟幕仿真研究

研究和完善烟幕的扩散模型，是烟幕测试和评价工作中的重要方面。烟幕爆炸后扩散具有分形特征，针对其扩散后的仿真问题，采用目前主要的烟幕爆炸数学模型，并结合分形布朗运动，运用随机中点位移法，对爆炸后烟幕的扩散进行了仿真。最后，利用无标度区间自动识别法对仿真烟幕数据结果进行了分析。

Research on Smoke Simulation with Fractional Brownian Motion

Researching and perfecting the model of smoke dispersion are important aspects in the smoke research and evaluation.Smoke characters fractal when it disperses after its explosion.This paper introduces the general mathematical model of smoke explosion and fractional Brownian motion and uses the method of random midpoint displacement to realize the simulation of smoke dispersion.Finally,the results of the simulated smoke are analyzed by the method of the auto-recognizing of scale-invariant space interval.
