Numerical Modeling of Two-Phase Seawater Flow in Oceanic Hydrothermal Systems using Parallel Computers

小行星9633531 标题：使用并行计算机对海洋热液系统中的两相海水流进行数值模拟 洋壳内的热液循环控制着洋中脊的地壳与海洋之间的热量和质量转移。我们无法看到这一过程的行动，因为它的不可访问性，但计算机模拟可以帮助我们了解发生的反应。这些反应很复杂，因为它们涉及高压下海水的沸腾，这可能是一个不稳定的过程。PI开发了一个计算机程序，模拟淡水通过陆地上的热液系统的循环，并将其应用于拉森峰。对海水沸腾的温度和压力以及无盐蒸汽和含盐盐水的形成的新测量将纳入这一计算机模型，以确定循环海水对海底下热液系统的影响。

9633531 Lowell Title: Numerical modeling of two-phase seawater flow in oceanic hydrothermal systems using parallel computers Hydrothermal circulation within the ocean crust controls both heat and mass transfer between the crust and the ocean at mid-ocean ridges. We can not view this process in action because of its inaccessibility but computer simulations can help us understand the reactions that occur. These reactions are complex because they involve the boiling of seawater under high pressure, which can be an unstable process. The PI has developed a computer program that simulates the circulation of fresh water through a hydrothermal system on land and has applied it to Lassen Peak. New measurements of the temperature and pressure of boiling of seawater, and the formation of salt-free vapor and salt-laden brine will be incorporated into this computer model to determine the effect of circulating seawater in a sub-seafloor hydrothermal system.
