In flight mechanics, “pulling up with load factor” refers to the action of increasing the angle of attack of an aircraft’s wings in such a way that the lift force generated by the wings exceeds the aircraft’s weight, causing the aircraft to experience an upward acceleration Cl​: This represents the lift coefficient, a dimensionless quantity […]

Radial velocity (Vr​) refers to the component of velocity of a fluid or object in the radial direction, which is directed outward from or inward toward a central point. In the context of a sphere, radial velocity specifically refers to the velocity component along a line that originates at the center of the sphere and

Tangential velocity (Vθ​) for a sphere refers to the component of velocity tangent to the surface of the sphere at a specific point. In other words, it is the velocity of a fluid or an object as it moves around the surface of the sphere, parallel to the surface. Tangential velocity (Vθ) in rad/s Angle

The term “combined flow” typically refers to a flow situation where multiple types of flow components or influences are present simultaneously. This can involve various factors such as uniform flow, rotational flow, or other flow patterns. If we consider a sphere experiencing combined flow, the radial velocity (Vr​) at a specific point on the sphere’s

Velocity potential (φ) is a scalar quantity that describes the fluid flow in terms of a scalar field. It represents the rate of change of fluid velocity with respect to spatial coordinates. In potential flow theory, the velocity components of the flow can be derived from the gradient of the velocity potential, which is why
