Isentropic expansion is a cornerstone concept in thermodynamics and fluid dynamics. It describes a process in which a gas expands while preserving its entropy, typically in an idealised, perfectly reversible and adiabatic pathway. In practice, engineers treat many real-world expansions as nearly isentropic to simplify design, analysis and optimisation. This article unpacks isentropic expansion in…
