k(T) law: models
Introduction
This section deals with the thermal conductivity k(T) from the point of view of the models provided by Flux.
Models
The numerous models provided are presented in the table below.
| Thermal conductivity k … |
|---|
| … isotropic/anisotropic, constant quantity (independent of temperature T) |
| … isotropic/anisotropic, linear function of T |
| … isotropic/anisotropic, exponential function of T |
| … isotropic/, tabulated function of T |
Specific models are also provided (see table below). Their mode of use is presented in § Spatial model / user model.
| Thermal conductivity k … |
|---|
| … spatial isotropic (k described via spatial formula) |
| … user (k described via user subroutine and personal version) |
