WebThermodynamic Data Thermodynamic data for individual species are necessary for performing equilibrium chemistry and finite-rate chemical kinetics calculations. These data typically provide the thermodynamic properties (enthalpy, entropy, and specific heat) of a species as a function of temperature. Sources of Data WebIt can be added that a higher heat capacity can clearly increase the heat transfer efficiency in the heat exchanger and the steam generators and, as a result, rise the efficiency of the whole system. Similar to the other thermophysical parameters of molten salt fuels, a few studies can be found in the literature that reposted a specific heat ...
