In aerodynamics, the lift coefficient (cl) is a dimensionless quantity that represents the efficiency of an airfoil or wing in generating lift. It quantifies the relationship between the lift force generated by the wing and certain aerodynamic parameters, such as the wing’s shape, angle of attack, and the properties of the fluid (usually air) it […]

In aerodynamics, “drag” refers to the aerodynamic force that opposes an object’s motion through a fluid, typically air. It acts parallel to the direction of the airflow and is a result of the resistance encountered by the object as it moves through the fluid medium. Drag is an important concept in aviation and other fields

In aerodynamics, “lift” refers to the force that acts on an aircraft wing (or any other aerodynamic surface) perpendicular to the oncoming airflow, enabling the aircraft to rise and counteract the force of gravity. Lift is one of the fundamental aerodynamic forces that allows an aircraft to become airborne and maintain controlled flight. Lift is

The “normal component of upstream Mach Number” refers to the component of the Mach number that is perpendicular (normal) to a specified reference direction. In fluid dynamics and aerodynamics, it’s common to analyze the flow of a fluid or the motion of an object in terms of its velocity components along different directions. The Mach

The Mach number behind a wave refers to the Mach number of a fluid or object at a specific point in a fluid flow immediately downstream (behind) of a shock wave. A shock wave is a type of propagating disturbance that occurs when a fluid (or gas) encounters a sudden change in its properties, such

In flight mechanics, the coefficient of viscosity of air refers to the dynamic viscosity of air, which is a measure of its resistance to deformation or flow. Dynamic viscosity is a fundamental property of fluids that quantifies the internal friction or “stickiness” between layers of fluid as they move past each other. It is a

The “Upstream Mach Number” refers to the Mach number of a fluid or object at a specific point in a fluid flow that is located upstream (i.e., in the direction against the primary flow of the fluid). The Mach number is a dimensionless quantity that characterizes the speed of an object or fluid relative to

“Velocity for upstream” generally refers to the speed of a fluid or object in a direction opposite to the flow of the fluid or the movement of the object. In fluid dynamics, the term “upstream” refers to the direction against the primary flow of the fluid. u2​: is the velocity of upstream  M2: is the

The Mach angle is an important concept in fluid dynamics and aerodynamics that describes the angle at which a shock wave or an object moving through a fluid medium (such as air) produces a cone of compressed air. When an object travels through a fluid at a speed greater than the local speed of sound,

The “velocity of the upper plate” refers to the speed at which the upper plate is moving relative to the stationary plate or relative to the fluid itself. The velocity of a fluid is a vector quantity, meaning it has both magnitude (speed) and direction. Similarly, the velocity of the upper plate would include both
