Lumped thermal element transporting heat without storing it
Thermal/HeatTransfer/Components
This is a model for transport of heat without storing it. It may be used for complicated geometries where the thermal conductance G (= inverse of thermal resistance) is determined by measurements and is assumed to be constant over the range of operations. If the component consists mainly of one type of material and a regular geometry, it may be calculated, e.g., with one of the following equations:
- Box Geometry (flow along length axis):
k: Thermal conductivity (material constant)
A: Area of box
L: Length of box
- Cylindrical Geometry (radial flow):
k : Thermal conductivity (material constant)
L : Length of cylinder
r_out: Outer radius of cylinder
r_in : Inner radius of cylinder
Typical Values for K at 20 degC in W/(m.K):
