Résumé	The Stefan-Maxwell diffusion equation describes how multiple chemical species diffuse through each other in a mixture, accounting for interactions between all species pairs. Unlike Fick's law, which assumes species diffuse independently, Stefan-Maxwell theory captures the coupling that occurs when species with different diffusivities move at different rates. This is essential for analyzing gas separation, combustion, catalytic processes, and reactive distillation.	The Vapor Compression Cycle is the fundamental thermodynamic cycle for refrigeration systems and heat pumps. It describes how mechanical work is used to transfer heat from a cold space (evaporator) to a warm space (condenser), operating against the natural temperature gradient. The cycle consists of four processes: isentropic compression, isobaric condensation, isenthalpic throttling, and isobaric evaporation.
