Free Stream Dynamic Pressure in Flow over Airfoils and Wings Formulas
Free Stream Dynamic Pressure is the kinetic energy per unit volume of fluid at some distance from the body where the density and velocity are freestream values. And is denoted by q
∞
. Free Stream Dynamic Pressure is usually measured using the Pascal for Pressure. Note that the value of Free Stream Dynamic Pressure is always positive.
