Volumetric heat capacity, linear function of T


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))


  • 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.
