Left: enthalpy-temperature diagram for isothermal (solid line) and mushy (dotted line) phase change. Right: capacity-temperature diagram shows a singularity for isothermal phase change (solid line) at \(T_m\). For the AC method the modified capacity \(c^*\) includes the effects of latent heat \(h_m\) within a regularized phase change interval \(\left[ T_s,T_l\right] \) similar to the mushy phase change type
