Information

1. Purpose of model

This model contains exemplary material data of basalt with temperature variant heat capacity and thermal conductivity. Both properties are approximated as polynomials in temperature.

2. Level of detail, physical effects considered, and physical insight

The properties of natural rock may vary significantly among quaries etc. This media model represent the measured data of the paper cited below.

3. Limits of validity

(Purely technical component without physical modeling.)

4.Interfaces

(no remarks)

5. Nomenclature

(no elements)

6. Governing Equations

(no equations)

7. Remarks for Usage

(no remarks)

8. Validation

(no validation or testing necessary)
