Low Speed to High Speed
Overview
Subsonic Flow refers to fluid flow where the flow velocity is lower than the speed of sound, common in aerodynamics, ventilation systems, and low-speed fluid dynamics. Transonic Flow occurs when fluid flow transitions from subsonic to supersonic speeds, typically around the speed of sound, relevant in aerodynamics, turbomachinery, and aircraft design. CFD simulations help analyze shock waves, flow separation, and aerodynamic performance in transonic conditions. Supersonic Flow refers to fluid flow where velocity exceeds the speed of sound, encountered in high-speed aerodynamics, propulsion systems, and aerospace applications.
