👉 The none fluid, often abbreviated as NF, is a concept in fluid dynamics that refers to the state of a fluid where no external forces (like gravity or pressure) are acting on it, resulting in an idealized, frictionless flow. In this scenario, the fluid behaves as if it were perfectly incompressible and inviscid, meaning it has no internal friction or resistance to flow. This theoretical model simplifies the analysis of fluid behavior, particularly in scenarios where real-world complexities like viscosity and turbulence are negligible. However, it's important to note that none fluid is an idealization and real fluids always exhibit some degree of viscosity and other dissipative effects.
