Mathematical Models for Magma-Hydrothermal Boundary Layer Heat Transfer at Ocean Ridge Crests

洛厄尔提出了两种大洋脊峰岩浆-热液边界层传热模型。其中一个模型将处理垂直热液边界层，这些边界层在堤坝附近发展，并随着羽流上升到海底。这种流动可能解释了似乎发生在岩浆穹顶边缘的短暂的黑烟活动。第二个数学模型涉及从对流、冻结的岩浆室到热液系统的热传递。该模型将侧重于海水的相分离和在热液系统底部形成的高盐度卤水层，以及这一层对岩浆-热液系统演化的后续影响。

Lowell proposes to develop two models for magma-hydrothermal boundary layer heat transfer at ocean ridge crests. One of the models will treat vertical hydrothermal boundary layers that develop adjacent to dikes and rise as plumes to the sea floor. This type of flow may explain ephemeral black smoker activity that appears to occur at the margins of magmatic domes. The second mathematical model concerns heat transfer from a convecting, freezing magma chamber to a hydrothermal system. This model will focus on phase separation of seawater and the formation of a highly saline brine layer at the base of the hydrothermal system, and the subsequent impact of such a layer on the evolution of the magma-hydrothermal system.
