Transonic flow is a term used in fluid dynamics to describe a flow regime in which the flow velocity is close to, but not exceeding, the speed of sound. This type of flow typically occurs in aerospace engineering, specifically in the design and analysis of high-speed aircraft and missiles. Transonic flow is characterized by the formation of shock waves and regions of supersonic and subsonic flow within the same flow field. Understanding and predicting the behavior of transonic flow is crucial in the design of aerodynamic structures to ensure efficient and stable performance at high speeds. Research in transonic flow typically involves computational fluid dynamics (CFD) simulations, wind tunnel testing, and theoretical analysis to study the complex interactions of compressible fluids in transonic regimes. This research area is essential for advancing the field of aerospace engineering and improving the performance and safety of high-speed vehicles.
