lumpedcapacity
Lumped capacity is a modeling technique used in various engineering disciplines, particularly in thermal, electrical, and fluid systems. It simplifies complex systems by representing distributed physical properties as discrete, or "lumped," elements. Instead of analyzing continuous variations in temperature, voltage, or pressure throughout a component, lumped capacity assumes that these properties are uniform within a defined region or element.
This simplification is based on the Biot number, a dimensionless parameter that compares the internal thermal
The primary advantage of using lumped capacity is the significant reduction in computational complexity. Instead of
However, the lumped capacity assumption is an approximation and has limitations. It is most accurate for objects
