【摘要】 本文介绍了一个可用于计算比重比空气太的烟羽扩散的数值模型的理论基础,该模型是荷兰德尔夫持大学Ooms教授等人建立并改进的。为了提高该模型预估值的准确性,文章引入了一组新的初始条件假设。通过和风洞实验结果相比较,发现新的初始条件得到的理论预估值更符合实际处理状态。更多还原

【Abstract】 This paper introduces a theoretical model for the dispersion of a stack plume with a density larger than air deveoped by Ooms et al. A new set of initial conditions is supplied in order to enhance the model predietions. It has shown more satisfactory agreement between the model predictions and the windtunnel experiment results.更多还原
