Classical fluid

Classical fluid refers to a model of fluid behavior that is described by classical mechanics and thermodynamics. These fluids are treated as continuous matter, allowing the use of macroscopic properties such as density, pressure, and temperature to describe their behavior rather than considering the individual molecules that make up the fluid. Key characteristics of classical fluids include: 1. **Continuum Assumption**: Classical fluids are assumed to be continuous materials, meaning that they can be modeled with fields (e.g.
