transsonique

Transsonic refers to an object or fluid moving at a speed greater than the speed of sound but less than the speed of supersonic shock. It is a transitional phase where the flow of an object or fluid is not yet supersonic but approaches sonic speed.

The term transsonic was coined by British engineer Frank McClure Whitmore in the 1920s to describe the flow regime between the subsonic and supersonic regimes. During transsonic flow, the object or fluid experiences a significant increase in drag, heat transfer, and excitation of sound waves.

Transsonic flow is often observed in aircraft design, particularly in the transitional region between subsonic and supersonic flight. In this regime, the flow around the aircraft's wings and fuselage becomes increasingly turbulent and complex, leading to a significant increase in drag and heat transfer.

Transsonic flow has been studied extensively in the field of aerodynamics, with a focus on understanding the transition between subsonic and supersonic flow regimes. Research in this area has led to the development of new design techniques and materials for aircraft and other high-speed vehicles.

The study of transsonic flow also has implications for fields such as meteorology and oceanography, where understanding the movement of fluids at transsonic speeds is crucial for predicting weather patterns and ocean currents.

Overall, transsonic flow is a complex and fascinating phenomenon that continues to be studied by researchers and engineers working to improve our understanding of high-speed fluid dynamics.
