👉 A split fluid, also known as a biphasic system, is a mixture of two immiscible liquids that separate into distinct phases or layers, each containing different components. This separation occurs due to differences in density, polarity, or other physical properties between the two liquids. Typically, one liquid is more soluble in the other, leading to the formation of two separate phases: one liquid dispersed throughout the other, often referred to as an emulsion or a dispersion. This phenomenon is common in various natural and industrial processes, such as oil and water mixtures, or the separation of components in chemical reactions. The interface between these phases can be stabilized by surfactants or other additives, preventing the liquids from fully mixing.
