摘要
本文运用电像法,把一个求解输送扩散方程的二维伪请模式发展成三维模式,尝试把高斯模式和数值计算模式结合起来运用于数值模拟。本文对水平风场内插方法进行了发展。摸拟结果表明:本文建立的一套模式是有效的,能够成功地摸拟污染物在城市地区的输送扩散行为。
Rased on a two-dimensional pseudo-spectral model by which a transport-diffusion equation is solved, a electric image method is used to develop a three-dimensional pseudo-spectral model. The numerical model is combined with Ganssian model to use in numerical modeling in the article, and interpolation used in the horizontal wind field is further developed. The result shows:the model in the article is effective to simulate transport and diffusion behavior of pollutants in urban area.
