The tool is designed to estimate the key thermophysical properties like Specific heat (at constant pressure and temperature), Enthalpy, Entropy, Polytropic index etc as a function of temperature at ambient pressure. The specific heat, enthalpy and entropy are estimated on both mole and mass specific basis. The estimation is based on seven coefficient NASA polynomials. To being with, the 53 species for which the coefficients are listed in the GRIMech 3.0 database (available at http://combustion.berkeley.edu/gri-mech/) are included and it is planned to extend the database to additional species. Currently, most of the species have a temperature range of 200 K to 3500 K and the plan is to subsequently extend the upper limit to about 6000 K by introducing new coefficients. The supported species are listed in the following table.
