"Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them."
Study of fluids in motion.
Properties of fluids: Introduces the basic properties of fluids like viscosity, surface tension, density, and compressibility.
Fluid statics: Covers the study of fluids at rest and the pressure and forces generated by fluids acting on surfaces.
Fluid dynamics: Covers the study of fluids in motion and the forces acting on solids immersed in fluids.
Fluid kinematics: Covers the study of the motion of fluids without considering the forces and energy involved.
Continuity equation: Expresses the conservation of mass principle applied to fluid flow, stating that the mass entering and leaving a system must be equal.
Bernoulli's equation: Relates the pressure of a fluid to its speed and height above a reference point.
Navier-Stokes equations: Describe the motion of viscous fluid substances and the forces acting on them.
Reynolds number: Dimensionless quantity used to predict fluid flow patterns and behavior.
Boundary layer: Refers to the thin layer of fluid in contact with a solid surface in which the fluid velocity is affected by the surface friction.
Turbulent flow: Refers to fluid flow that is characterized by chaotic and unpredictable changes in velocity and pressure.
Laminar flow: Refers to fluid flow that is characterized by smooth, parallel layers of fluid with no mixing between layers.
Drag: Force exerted by a fluid on an object moving through it, opposite to the direction of motion.
Stokes' law: Describes the relationship between the drag force acting on a small sphere in a viscous fluid and the velocity of the sphere.
Compressible flow: Refers to fluid flow in which the density of the fluid changes significantly due to changes in pressure, temperature, or velocity.
"It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology."
"It can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion."
"It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic."
"Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex."
"Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers."
"A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach."
"Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow."
