111Cottrell equation — In electrochemistry, the Cottrell equation describes the change in electric current with respect to time in a controlled potential experiment, such as chronoamperometry. Specifically it describes the current response when the potential is a step… …
112Équations aux dérivées partielles — Équation aux dérivées partielles En mathématiques, plus précisément en calcul différentiel, une équation aux dérivées partielles ou équation différentielle partielle (EDP) est une équation dont les solutions sont les fonctions inconnues vérifiant …
113DÉRIVÉES PARTIELLES (ÉQUATIONS AUX) - Sources et applications — On se propose de décrire très sommairement quelques types classiques d’équations aux dérivées partielles issues principalement de la physique et de préciser leurs interventions dans des domaines variés des mathématiques. Alors que les solutions… …

117Cylindrical harmonics — In mathematics, the cylindrical harmonics are a set of linearly independent solutions to Laplace s differential equation, , expressed in cylindrical coordinates, ρ (radial coordinate), φ (polar angle), and z (height). Each function Vn(k) is the… …
118Potential 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,… …
119fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …
120Parabolic cylindrical coordinates — are a three dimensional orthogonal coordinate system that results from projecting the two dimensional parabolic coordinate system in theperpendicular z direction. Hence, the coordinate surfaces are confocal parabolic cylinders. Parabolic… …
