👉 The represented fluid, often referred to as a pseudofluid or a theoretical fluid in the context of fluid dynamics and continuum mechanics, is an idealized model used to describe the behavior of real fluids under various conditions. It simplifies the complex interactions between fluid molecules by assuming they behave as a continuous, homogeneous substance that obeys specific mathematical equations, such as the Navier-Stokes equations. This fluid is characterized by properties like viscosity, density, and pressure, which are averaged over the microscopic interactions of its constituent particles. By treating fluids as these represented fluids, engineers and scientists can more easily analyze and predict fluid behavior in engineering applications, from aerodynamics to pipeline flow, without needing to account for the intricate details of molecular interactions.
