In fluid mechanics, the momentum equation is a direct application of Newton’s second law of motion to a moving fluid. […]

In fluid mechanics and aerodynamics, the continuity equation expresses the principle of conservation of mass. It ensures that mass cannot

In aerodynamics, before we even write the famous equations for conservation of mass, momentum, or energy, we need to ask:

In two-dimensional, incompressible flow, two scalar functions are widely used to describe the velocity field: the stream function and the

In fluid dynamics, angular velocity and vorticity are fundamental concepts used to describe the rotational characteristics of fluid elements. While

In fluid mechanics and aerodynamics, flow visualization is essential to understand how fluid moves around objects. Three fundamental concepts used

Fluid flow can be classified in many ways based on physical behavior such as time dependence, compressibility, viscosity, rotation, and
