Lumped capacitance modeling is a simplified approach used in thermal analysis to represent an object as a single node with a uniform temperature. This method is valid when the internal thermal resistance of the object is significantly smaller than its external convective or radiative thermal resistance. In essence, it assumes that heat transfer within the object is much faster than heat transfer to or from its surroundings, allowing the entire object to be treated as if it has a single, well-mixed temperature.
The core principle of lumped capacitance analysis is that the Biot number (Bi) is small. The Biot
When the lumped capacitance model is applicable, the transient heat conduction problem simplifies dramatically. The temperature
