Fluid Mechanics/Unit 1/ Types of Fluid Flow/Lecture 8

Fluid flow is a fundamental concept in fluid mechanics, describing the motion of fluid substances such as liquids, gases, and plasmas. The study of fluid flow encompasses various types, including ideal fluid, real fluid, Newtonian fluid, and non-Newtonian fluid. Ideal fluids are theoretical and incompressible with no viscosity, while real fluids account for viscosity and compressibility. Newtonian fluids have a constant viscosity independent of the stress applied, like water and air, whereas non-Newtonian fluids exhibit a change in viscosity with varying stress, such as toothpaste and ketchup. Understanding these types is crucial for applications in engineering, physics, and natural sciences.
