In laminar, incompressible flow, the flat plate skin-friction drag coefficient (Cf) is a dimensionless parameter that quantifies the amount of skin-friction drag experienced by a flat plate immersed in the fluid. Skin-friction drag is a type of drag force that results from the interaction between the fluid and the solid surface of the flat plate, […]

The lift slope (also known as the lift curve slope or lift coefficient slope) for a finite wing refers to the rate of change of lift coefficient (CL) with respect to angle of attack (α). It quantifies how the lift produced by the wing changes as the angle of attack is varied.  a: Lift slope

The Mach number (Ma) in terms of the velocity of the upper plate (ue) and the local speed of sound in the fluid (c or sometimes denoted as a). It applies to compressible flow situations where the density of the fluid changes significantly due to variations in pressure and temperature.  Me: Mach number (dimensionless). ue:

The Reynolds number for Couette flow is a dimensionless quantity used in fluid mechanics to characterize the flow regime in a specific type of flow known as Couette flow. Couette flow is a type of laminar flow that occurs between two parallel plates when one plate is moving and the other is stationary. Re: Reynolds

Shear stress (τ) is a fundamental concept in mechanics and fluid dynamics that quantifies the force per unit area acting parallel to the surface of a material or fluid element. It describes the internal resistance of a material to deform when subjected to tangential or shearing forces.  τ: Shear stress in the fluid in  N/m²

Total enthalpy, denoted as h0, is a thermodynamic property used to describe the total energy content of a fluid stream, which includes both the internal energy and the flow energy. Enthalpy is a fundamental concept in thermodynamics, especially in the study of fluid dynamics and heat transfer.  h is the specific enthalpy of the fluid

The test section air velocity in a wind tunnel refers to the speed or magnitude of the airflow within the specific region of the wind tunnel where aerodynamic or fluid dynamics experiments are conducted. The test section is the part of the wind tunnel where models, aircraft, vehicles, or other objects are placed to study

The test section air velocity in a wind tunnel refers to the speed or magnitude of the airflow within the specific region of the wind tunnel where aerodynamic or fluid dynamics experiments are conducted.

The velocity of a wind tunnel refers to the speed of the airflow within the tunnel. Wind tunnels are specialized facilities used in aerodynamics and fluid dynamics research to study the behavior of air and other fluids around objects, such as aircraft, vehicles, buildings, and various engineering structures.  V1 is the inlet velocity V2 is

The displacement of a body refers to the change in position of the body relative to a reference point or a starting position. It is a vector quantity that specifies both the distance and direction of the object’s movement. Displacement is different from distance, which is the total length of the path traveled by the
