The “induced angle of attack” (𝛼i) is an aerodynamic concept that describes the additional angle of attack experienced by an aircraft’s wing due to the generation of lift. It is caused by the wing’s vortices, which are swirling masses of air that form at the wingtips when the aircraft generates lift.  𝛼i is the induced […]

The Kutta-Joukowski theorem is a fundamental principle in aerodynamics that relates the lift force generated by an airfoil to the circulation around the airfoil in potential flow theory. It provides a mathematical relationship between the lift, fluid velocity, and the geometry of the airfoil in a simplified, inviscid flow scenario.  L = Lift force acting

Induced drag coefficient (CDi) is a dimensionless parameter used in aerodynamics to quantify the efficiency of a lifting object, such as an aircraft wing or a rotor blade, in generating lift while also accounting for the drag induced by the generation of lift. CDi: Induced drag coefficient Di: Induced drag force q∞: Dynamic pressure of

The radial velocity for a source flow refers to the component of velocity that is directed radially away from or towards a central point source of fluid. A source flow is an idealized model in which fluid is continuously emanating from a point source (or converging towards a point sink).  Vr: Radial velocity component in

The profile drag coefficient (Cd) is a dimensionless quantity used in fluid mechanics and aerodynamics to characterize the resistance experienced by an object as it moves through a fluid, such as air or water. It is a measure of the drag force generated due to the interaction between the object’s surface and the fluid. Profile

In the context of fluid mechanics and potential flow theory, the radius of a circular cylinder is related to the strength of a doublet and the free-stream velocity through the concept of flow around a cylinder with a doublet. R: Radius of the circular cylinder 𝜅: The strength of the doublet V∞: The free-stream velocity

The radial velocity (Vr) component of fluid flow around a circular cylinder refers to the fluid velocity perpendicular to the axis of the cylinder at a given radial distance from its center. This component of velocity describes how the fluid moves towards or away from the center of the cylinder in the radial direction.  Vr

The height difference in a manometer refers to the difference in the fluid column levels between the two arms of the manometer. A manometer is a simple device used to measure pressure differences in a fluid system. It consists of a U-shaped tube filled with a liquid (often mercury or water) and connected to the

The velocity, V1, in a Pitot tube refers to the fluid velocity at the specific location of the Pitot tube in a fluid flow. The Pitot tube is an instrument used to measure the velocity of a fluid, particularly in applications like aerodynamics and fluid mechanics. V1 is the velocity at the location of the

The velocity at the exit of a diffuser refers to the fluid velocity of a flow exiting a diffuser section in a fluid system. A diffuser is a flow passage in which the cross-sectional area gradually increases in the direction of flow. It is designed to slow down the fluid and increase its pressure.  V2
