摘要
采用高斯扩散方程建立了烟雾扩散-衰减控制模型,介绍了参数的确定。基于建立的模型,研究了烟雾突增条件下,单一火灾点源在稳定风场作用下及两个点源共同作用时的烟雾高斯扩散-衰减规律,并讨论了该模型的合理性。
Based on the Gaussian diffusion equation,a diffusion attenuation model for fire smoke was established,and the parameters were decided.When the fire smoke increases quickly,both the single point source fire under stable wind field and two concurrent sources situations were analyzed for the diffusion and attenuation regularity of fire smoke.Finally,the reasonability and shortage were discussed.
