41AÉRODYNAMIQUE — L’aérodynamique, dont l’étymologie évoque immédiatement l’action de l’air en mouvement, est la science qui étudie les différents aspects de cette action, notamment les forces, pressions et moments qui résultent du déplacement des corps dans… …
42Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …

44Buoyancy — The forces at work in buoyancy In physics, buoyancy (  / …
45Derivation of the Navier–Stokes equations — The intent of this article is to highlight the important points of the derivation of the Navier–Stokes equations as well as the application and formulation for different families of fluids. Contents 1 Basic assumptions 2 The material derivative 3 …

47BICKLEY — UNITED KINGDOM (see also List of Individuals) 19.4.1893 Stantonbury/UK 4.7.1969 Northwood/UK William George Bickley gained his BSc in 1912 from the University College, Reading, his MSc in 1920 and the PhD title in 1930. In parallel, he was until… …
48Euler equations (fluid dynamics) — In fluid dynamics, the Euler equations govern inviscid flow. They correspond to the Navier Stokes equations with zero viscosity and heat conduction terms. They are usually written in the conservation form shown below to emphasize that they… …
49Rayleigh flow — refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible… …
50Dynamic pressure — In incompressible fluid dynamics dynamic pressure (indicated with q, or Q, and sometimes called velocity pressure) is the quantity defined by:[1] where (using SI units): = dynamic pressure in pascals …
