Document Summary
Fluid mechanics is the study of fluids either in motion (fluid dynamics) or at rest (fluid statics). Since the earth is 75% covered with water and 100% with air, the scope of fluid mechanics is vast and has numerous applications in engineering and human activities. It is possible to apply numerical techniques to complex geometries, this branch of fluid mechanics is called computational fluid mechanics (cfd). The theory first yield the frictionless assumption which led to several beautiful mathematical solutions. Leonhard euler (1707 1783) developed both the differential equations of motion and their integral form, now called bernoulli equation. Navier (1785 1836) and stokes (1819 1903) added newtonian viscous term to the equation of motion, the fluid motion governing equation, i. e. , navier stokes equation is named after them. Liquids: are composed of relatively close packed molecules with strong cohesive forces. Liquids have constant volume (almost incompressible) and will form a free surface in a gravitational field if unconfined from above.
