Flow direction refers to the path that a fluid takes as it moves through a system, influenced by factors like pressure, viscosity, and external forces. Understanding flow direction is crucial because it impacts the behavior of fluids in various applications, including heat transfer and mass transport phenomena. In multiphase flow, knowing the flow direction helps in predicting how different phases will interact with one another, which is essential for processes such as mixing, separation, and chemical reactions.
