Difference between Lumped element model and Thermal conduction

Lumped element model vs. Thermal conduction

The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body.

Heat transfer coefficient

The heat transfer coefficient or film coefficient, or film effectiveness, in thermodynamics and in mechanics is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT): The overall heat transfer rate for combined modes is usually expressed in terms of an overall conductance or heat transfer coefficient, U. In that case, the heat transfer rate is: where: The general definition of the heat transfer coefficient is: where: It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid.

Newton's law of cooling

Newton's law of cooling states that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its surroundings provided the temperature difference is small and the nature of radiating surface remains same. As such, it is equivalent to a statement that the heat transfer coefficient, which mediates between heat losses and temperature differences, is a constant.
