This makes the color of the crystal become dull. Kerosene can keep air away from the crystal. It can be also used to prevent air from re-dissolving in a boiled liquid, [58] and to store alkali metals such as potassium, sodium, and rubidium (with the exception of lithium, which is less dense than kerosene, causing it to float).

In fluid dynamics, the Buckley–Leverett equation is a conservation equation used to model two-phase flow in porous media. [1] The Buckley–Leverett equation or the Buckley–Leverett displacement describes an immiscible displacement process, such as the displacement of oil by water, in a one-dimensional or quasi-one-dimensional reservoir.
