What is fluid dynamics concerned with?

Fluid dynamics is a specialized branch of fluid mechanics that focuses on the behavior and processes of fluids in motion. This area of study examines how fluids interact with solid boundaries, which includes understanding the forces and flow patterns generated when fluids, such as liquids and gases, move.

Fluid dynamics employs fundamental principles, such as conservation of mass, momentum, and energy, to analyze and predict the behavior of fluid flows under various conditions and constraints. The interactions between moving fluids and surfaces are crucial in a wide range of applications, from aerodynamics in aviation to hydraulics in civil engineering.

The other areas mentioned pertain to different aspects of fluid mechanics, but do not encapsulate the primary focus of fluid dynamics. For example, the study of fluids at rest is known as hydrostatics, while thermodynamic processes relate more closely to the principles governing temperature and heat transfer in fluids, rather than their motion. Fluid chemical properties would focus on the composition and reactions of fluids rather than the physical movements and dynamics associated with them.
