خلاصهThe 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.The Lumped Capacitance Method is a simplification technique for solving unsteady-state heat transfer problems. It assumes that thermal properties are uniform throughout a solid body and that temperature variations within the object are negligible. This approach enables engineers to solve complex transient heat conduction problems using ordinary differential equations rather than partial differential equations.
