The Euler Equations are a set of fundamental equations in fluid dynamics that describe the motion of an inviscid fluid, meaning a fluid with no viscosity. They are derived from the principles of conservation of mass, momentum, and energy. These equations help predict how fluids behave under various conditions, making them essential in fields like engineering and meteorology. In addition to fluid dynamics, Leonhard Euler, the Swiss mathematician and physicist, formulated these equations in the 18th century. The equations are often expressed in terms of velocity, pressure, and density, providing a mathematical framework for analyzing fluid flow in various applications, from aerodynamics to oceanography.
