弥散相蒸发高度是蒸发弥散相工程设计中最重要的参数之一。很明显，此高度是以统计特性表明出来的，因为蒸发气泡的尺寸不是均匀的而是有一定的范围。为便于解决问题，使颗粒数平衡方程形成一个框架。基于此，该文建立了数学物理模型，它考虑了气泡的破裂和聚合。使用作者近年来提出的分裂＋类比的方法，数值模拟了统计蒸发高度。数值模拟结果在定性上和定量上与实验都有较好的一致性，数值实践表明，在本文研究的系统中气泡破裂是主要的，并且很强。
Diffusion phase evaporation height is one of the most important parameters in the engineering design of evaporative disperse phase. Obviously, this height is indicated by statistical properties because the size of the evaporative bubbles is not uniform but rather ranges. In order to solve the problem, the particle number balance equation forms a framework. Based on this, the paper established a mathematical physics model, which considers the bubble rupture and polymerization. Using the method of split + analog proposed by author in recent years, the height of statistical evaporation is numerically simulated. The results of numerical simulation are qualitatively and quantitatively consistent with the experimental results. Numerical experiments show that the bubble rupture is dominant and strong in the system studied in this paper.
