The Prandtl-Meyer function, often denoted as ν(M), is a mathematical function used in the study of compressible fluid dynamics, particularly for analyzing the expansion of a flow over a wedge or a curved surface. The function describes the angular deviation of the flow caused by a Mach wave (a type of compression wave) in supersonic […]

The Mach number behind the reflected wave, often denoted as M3​, represents the speed of the flow relative to the local speed of sound in the region behind a reflected shock wave. It quantifies the velocity of the flow in relation to the speed at which pressure disturbances propagate through the fluid.  Mach number behind

The “reflected shock to the upper wall angle,” often denoted as Φ, refers to the angle formed between a reflected shock wave and the upper wall of a duct or channel in fluid flow. This concept is commonly encountered in the study of compressible fluid dynamics, particularly in scenarios where shock waves interact with boundaries. 

The wave drag coefficient for a wedge is a dimensionless quantity that characterizes the additional drag experienced by an object moving at supersonic speeds due to the formation of shock waves and wave patterns in the airflow around the object. Wave drag is a type of drag that becomes significant as an object approaches or

In the context of a wedge in aerodynamics, dynamic pressure (q1​) is a measure of the kinetic energy per unit volume of the fluid flowing around the wedge shape. It represents the pressure increase that would occur if the fluid were brought to a complete stop, converting all of its kinetic energy into pressure energy.

The drag coefficient for a wedge is a dimensionless quantity that characterizes the aerodynamic drag of a wedge-shaped object moving through a fluid. It’s a valuable parameter in aerodynamics and is used to quantify how efficiently a wedge shape interacts with the fluid flow.  Drag coefficient (cd) Wedge angle (𝜃) in rad Pressure over the

The “drag on a unit span of the wedge,” often denoted as D′, refers to the aerodynamic force acting on a unit span (usually 1 meter) of a wedge-shaped object due to the airflow around it. This force is known as drag, and D′ specifically quantifies the drag force per unit span length.  Drag on

The total pressure across a shock wave in a supersonic flow, denoted as p0,2​, is the sum of the static pressure and the dynamic pressure after the flow has passed through the shock. It represents the total energy of the flow, which includes both pressure energy and kinetic energy due to the flow velocity.  Total
