Thermal model of a hollow cylinder by Fourier's equation - 1 axial
node and Nr radial nodes
This is the 1D thermal model of a solid hollow cylinder by
Fourier's equations.
The model is axis-symmetric, has one node in the longitudinal
direction, and Nr nodes in the radial direction. The two
connectors correspond to the internal and external surfaces; if one
of the surface is thermally insulated, just leave the connector
unconnected (no connection on a DHT connector means zero
heat flux). The temperature-dependent properties of the material
are described by the replaceable MaterialModel model.
Modelling options
The radial distribution of the nodes can be chosen by selecting the
value of nodeDistribution:
- Choices.CylinderFourier.NodeDistribution.uniform
uniform distribution, nodes are equally spaced;
- Choices.CylinderFourier.NodeDistribution.thickInternal
quadratic distribution, nodes are thickest near the internal
surface;
- Choices.CylinderFourier.NodeDistribution.thickExternal
quadratic distribution, nodes are thickest near the external
surface;
- Choices.CylinderFourier.NodeDistribution.thickBoth
quadratic distribution, nodes are thickest near both surfaces.
