👉 Preliminary fluid, often referred to as the initial fluid or early fluid phase, is a transient liquid state that forms during the early stages of a fluid dynamic process, typically before the complete breakdown of the fluid into its constituent components. This phase occurs when a fluid is subjected to rapid changes in conditions such as pressure, temperature, or velocity, leading to the formation of droplets or small liquid clusters. These preliminary fluids are crucial in understanding the initial stages of phenomena like droplet formation, breakup, and mixing, as they set the stage for subsequent fluid behavior and interactions.
