Hüdrodünaamikas

Hüdrodünaamikas, also known as Hydrodynamics, is a branch of fluid dynamics that deals with fluid flows that are viscous and involve the study of the motion of fluids. It is distinct from hydrostatics, which deals with fluids at rest. Hydrodynamics typically refers to the study of liquids, while the study of gases is often referred to as aerodynamics, though the principles can overlap significantly.

The fundamental principles of hydrodynamics are based on conservation laws, particularly conservation of mass, momentum, and energy. These principles are often expressed mathematically through equations such as the Navier-Stokes equations, which describe the motion of viscous fluid substances. Key concepts within hydrodynamics include pressure, velocity, viscosity, and density.

Applications of hydrodynamics are vast and fundamental to many fields. In engineering, it is crucial for the design of ships, submarines, pumps, turbines, and pipelines. Understanding fluid flow is also essential in meteorology for weather forecasting, oceanography for studying ocean currents, and biology for understanding blood flow in living organisms. The behavior of water in rivers, lakes, and oceans is also a primary subject of hydrodynamic study. Its principles are applied to solve complex problems ranging from the large-scale circulation of the atmosphere and oceans to the micro-scale movement of fluids in biological systems.
