Aerothermodynamics
Definition
An advanced branch of fluid mechanics and thermodynamics that studies the behavior, physical properties, and thermal phenomena of airflows moving at extremely high speeds (supersonic and hypersonic). This structural science analyzes the complex interactions between aerodynamic forces and the intense heat transfer generated by gas friction, being essential for the design of rockets, space shuttles, and atmospheric re-entry vehicles.
