The\u00a0fluid mechanics<\/b>\u00a0is the branch of\u00a0mechanics<\/a> which studies the motion of fluids (liquids and gases) and the forces that cause it. This also involves the interactions between the fluid and the boundary that limits it.<\/p>\n

The distinguishing characteristic of fluids is their inability to resist shear stresses. It is also important to consider the compressibility of fluids. Liquids are usually considered incompressible and gases compressible, although in some aerodynamic applications the volume difference of air is considered to be zero.<\/p>\n

HYPOTHESES IN FLUID MECHANICS<\/h2>\n

CONCEPT OF A CONTINUOUS MEDIUM<\/span><\/h3>\n

 <\/p>\n

The continuous medium hypothesis is a fundamental hypothesis of fluid mechanics. In this hypothesis, the whole fluid is considered as a continuous whole without taking into account any discontinuities it may have. The properties of pressure and temperature are considered to be continuous throughout the fluid.<\/p>\n

FLUID PARTICLE CONCEPT<\/span><\/h3>\n

The fluid particle is the mass of fluid that at a given instant is at a given point. It must be large enough to have a large number of molecules and small enough to be able to consider that there are no variations in its macroscopic properties inside.<\/p>\n

GENERAL EQUATIONS OF FLUID MECHANICS<\/h2>\n

 <\/p>\n

The\u00a0general equations <\/b>to describe the motion of a fluid are the Navier-Stokes equations. They are a set of very complex equations with which to describe the movements in the Earth's atmosphere, ocean currents, flow around vehicles and any Newtonian fluid movement. These equations are obtained by applying the conservation principles of mechanics and thermodynamics to a fluid volume.<\/p>\n

The mission of this website is to explain the science<\/a> In a simple form and these equations are of great complexity, involving derivatives, integrals and very complex calculations that do not allow to focus on the science behind the problem, we will assimilate the equations of fluid mechanics to the <\/p>\n

Bernoulli's principle differs from the complex Navier Stokes equations (for which computer resources are needed) in that Bernoulli's is for an ideal fluid (no viscosity and no thermal conductivity).<\/p>\n
