WebOne challenge involved in the modeling is that PCM specific heat increases during phase change. Hsiao [119] proposed a piecewise specific heat function in terms of temperature for numerical simulation of the phase change process. For a pure material, it has a sharp freezing/melting temperature, and thus a small temperature interval is desirable ... WebSpecific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat (Cp) is used for substances in a constant pressure (ΔP = 0) system. Isochoric specific heat (Cv) is used for substances in a constant-volume, (= isovolumetric or isometric) closed system.
