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

题目：用并行计算机模拟海洋热液系统中两相海水流动的数值模拟洋壳内的热液循环控制着洋中脊处地壳与海洋之间的热量和质量传递。由于难以接近，我们无法观察到这一过程的实际情况，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，因为它们涉及海水在高压下沸腾，这可能是一个不稳定的过程。PI开发了一个计算机程序，模拟淡水通过陆地热液系统的循环，并将其应用于拉森峰。对海水沸腾时的温度和压力的新测量，以及无盐蒸汽和含盐盐水的形成将被纳入这个计算机模型，以确定海底热液系统中循环海水的影响。

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.
