Summary

Value from a polynomial function

Description

$c_p = R(C_0 + \sum_\text{n=1}^{\text{order}} C_i (T + T_{off})^n)$

where $T_{off}$ is set by the “VARIABLE_OFFSET” parameter.

An enthalpy evaluator is automatically provided, the reference state temperature, enthalpy, and entropy can optionally be provided via the T_standard, h0, and s0 parameters. All default to 0 if they are not provided.
