Résumé	The Boussinesq Approximation simplifies the governing equations for natural convection by treating density as constant except in the buoyancy term. This approximation is valid when temperature variations produce small density changes and allows researchers to solve coupled heat-fluid flow problems without solving the full, nonlinear compressibility equations. The Boussinesq Approximation is fundamental to analyzing buoyancy-driven flows in buildings, enclosures, and geophysical applications.	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.
