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 Thermal Resistance Network method uses electrical circuit analogy to solve heat transfer problems. It treats heat flow as analogous to electric current, thermal resistance analogous to electrical resistance, and temperature difference analogous to voltage potential. This powerful conceptual framework enables engineers to analyze complex multi-layer heat transfer systems systematically.
