lumped characteristic
1Lumped capacitance model — A lumped capacitance model, also called lumped system analysis,[1] reduces a thermal system to a number of discrete “lumps” and assumes that the temperature difference inside each lump is negligible. This approximation is useful to simplify… …
2Lumped element model — In general, the lumped component model is a way of simplifying the behaviour of spatially distributed systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It… …
