Supersonic flow is characterized by speeds faster than the speed of sound. It is often used in applications such as supersonic aircraft, missiles, and high-speed wind tunnels. Supersonic flow can create shock waves and high temperatures, making it challenging to control and design for.
Subsonic flow in fluid dynamics refers to flow where the speed of the fluid is less than the speed of sound. Characteristics include smooth and predictable flow patterns, low pressure gradients, and the absence of shock waves. Applications include aircraft design, ventilation systems, and automotive aerodynamics.
Supersonic flow occurs when the fluid velocity exceeds the speed of sound in the medium, resulting in shock waves forming. This can happen in situations such as a jet aircraft flying faster than the speed of sound or a rocket accelerating to supersonic speeds. The behavior of such flow is influenced by compressibility effects, leading to unique aerodynamic phenomena.
Critical flow in fluids refers to the condition where the flow velocity in a fluid reaches the speed of sound. This is the point at which the flow transitions from subsonic to supersonic and is associated with significant changes in flow properties. Critical flow is important in various fluid dynamics applications, such as in nozzles and Venturi tubes.
The small size of the working area in a supersonic tunnel is necessary to create the high-speed, high-pressure airflow required for testing at supersonic speeds. Restricting the area helps achieve the desired air velocities and pressures necessary for accurate testing of aerodynamic properties. Additionally, the smaller working area allows for better control and measurement of flow characteristics.
The mach cone angle is important in supersonic flow dynamics because it represents the angle at which shock waves propagate from an object moving faster than the speed of sound. Understanding this angle helps researchers analyze and predict the behavior of supersonic flow around objects, such as aircraft or projectiles, which is crucial for designing efficient and safe aerodynamic systems.
Supersonic flow is produced in a de laval nozzle by constricting the flow in the center in order to increase the velocity. The shape will be hour-glass in nature. The initial mass flow rate and inlet pressure must be sufficient to produce a supersonic choked flow and the discharge pressure must be sufficiently low enough for supersonic flow to occur.
Supersonic waves are used in supersonic flights. They are also used in body scanning and used to detect faults in metal.

It affects drag and supersonic flight characteristics, which is why supersonic aircraft generally have long noses.
Convergent-divergent nozzles are used in steam applications to efficiently accelerate steam to supersonic speeds. The convergent section of the nozzle compresses the flow, increasing its velocity as it approaches the speed of sound, while the divergent section allows the steam to expand further, achieving supersonic flow. This design maximizes the energy conversion from thermal to kinetic energy, enhancing the overall efficiency of steam turbines and other systems. Additionally, it helps control the pressure and flow characteristics of the steam, optimizing performance in various operating conditions.

Using shock-expansion cancellation technique flow in the diverging part of a supersonic nozzle is brought back to free stream direction ( direction parallel to the axis of nozzle) where a rhombus shaped region(Test Section) is formed in which uniform flow is ensured.
