Measured continuous cooling curves by Ahmed et al. [33] along with the corresponding model-based curves resulting from the identified temperature-dependent parameter g(T) from Eqs. (25) and (24). The a-, b-, c- and d-curve were measured at positions \(x_a=3.2\ mm\), \(x_b=9.5\ mm\), \(x_c=12 \ mm\) and \(x_d=15.2\ mm\) at otherwise identical cooling conditions
