Volumetric heat capacity, linear function of T
Presentation
This model defines a volumetric heat capacity ρCp as a linear function of the temperature for an isotropic or anisotropic material.
Mathematical model
The volumetric heat capacity is a linear function of the temperature.
The corresponding mathematical formula is written:
ρCp(T)= ρCpa (1+a (T - T0))
where:
- T0 is the reference temperature (degree)
- ρCpa is the volumetric heat capacity at T0 (J/m3/degree)
- a is a coefficient (positive or negative) (degree-1)
The shape of ρCp(T) curve is presented in the figure below.
