Abstract

In extracting Gaussian plume parameters from transverse profiles of concentration measured in model or full-scale tests of dispersion from an elevated source, a common practice is to employ a statistical best-fit procedure in conjunction with the general equation. This involves 1) a calculation of x by Equation 1 for each data point (y,z) using known parameter Q and combinations of assumed parameters sigma/sub y/, sigma/sub z/, u and H; 2) a comparison of calculated and observed values of x; and 3) minimization of the discrepancy for the complete data set.

浓度垂直剖面的σZ和H计算
在从高源色散的模型或全尺寸试验中测量的浓度横向剖面中提取高斯羽流参数时,通常的做法是结合一般方程采用统计最佳拟合程序。这涉及1)使用已知参数Q和假设参数sigma/下标y/、sigma/下标z/、u和H的组合,通过公式1计算每个数据点(y,z)的x;2) x的计算值与实测值的比较;3)最小化完整数据集的差异。
