LOW-SPEED AERODYNAMICS EQUATIONS OVERVIEW Continuity Equation Cartesian coordinates: r r dV + (V n )dA = 0 t CV The equation used is based on the usual condition of zero flow normal to the surface. If the speed of the gas is much less than the speed of sound of the gas, the density of the gas remains constant and the velocity of the flow increases. For 3-D wings the condition is applied at several span-wise sections by matching flow and surface angles. However, if you hone in on the most important thermodynamic formulas and equations, get comfortable converting from one unit of physical measurement to another, and become familiar with the physical constants related to thermodynamics, you’ll be at the head of the class. The complex science of aerodynamics can help us understand precisely how the air flows over the surface of the ball, allowing it to fly through the air like a plane rather than take on the trajectory of a bullet.
