Abstract Two-phase flow and phase separation is an essentially ubiquitous feature of high temperature hydrothermal circulation at ocean ridges. This project will continue efforts toward developing a finite difference based numerical code for a NaCl-H2O solution and applying it to a number of first order seafloor hydrothermal problems. Tasks to be addressed include further modeling of 1-D heat pipe systems, modeling of 1-D systems including mass flux from below, modeling of 2-D circulation near a dike, and general 2-D circulation in a single-pass model.

摘要 两相流和相分离是洋脊高温热液环流的一个本质上普遍存在的特征。 该项目将继续努力开发基于有限差分的 NaCl-H2O 解决方案数值代码，并将其应用于许多一阶海底热液问题。 要解决的任务包括一维热管系统的进一步建模、一维系统的建模（包括来自下方的质量通量）、堤坝附近的二维循环建模以及单通道模型中的一般二维循环。
