流动环境中倾斜浮力射流的积分方法

An Integral Method for Inclined Buoyant Jets in Flowing Ambients

给出了基于积分方法的一种倾斜浮力射流的数学模型,且流速、密度和浓度差剖面假定为高斯分布,并导出了用来封闭该数学模型的较为完全的掺入率公式。用计算精度较高的有限分析法计算这类定解问题,计算结果与试验资料基本吻合。

An integral model of buoyant jets is given in this paper. The profiles for velocity density and concentration difference are assumed to be Gaussian distribution, and the relations of the entrainment rate with local densimetric Froude number and cross velocity are derived for closing the governing equations. The Finite Analytic Method is used to solve this problem. The calculated results of the inclined buoyant jets are well compared with the experimental data.
