Lumped parameter models are a type of reduced-order model that discretize a physical system into lumps.[^1] System behavior is evaluated at the nodes between lumps.[^1] Lumped parameter models can be used under the following conditions:
- 1) The characteristic length of the maximum lump size is less than the smallest wavelength of the phenomenon that will be encountered
- 2) the connections between lumps only provide topological information
- 3) information is passed between lumps instantly.
Point Reactor Kinetics Model – lumped-parameter model
Thermal Hydraulic Reactor Model – lumped model
[[Gas Path Dynamics]] – can be approximated using a lumped model
Equivalent Reduced Wing Structure– lumped-parameter mass vibration model
[[TRIGA MK 2 Reactor]] – uses a lumped parameter model
[[State-Space Model]] – lumped parameters for linear electric circuits
Fuel Rod Thermal Model – fuel temperature is obtained from a lumped model energy balance
U-tube Steam Generator Model– uses a lumped parameter technique
[[Bond Graphs]] – are a form of lumped parameter model
