Nasa polynomial list for different species
http://web.mit.edu/2.62/cantera/doc/html/classCantera_1_1Nasa9Poly1.html WitrynaThe NASA polynomial is another representation of the heat capacity, enthalpy, and entropy using seven or nine coefficients a = [ a − 2 a − 1 a 0 a 1 a 2 a 3 a 4 a 5 a 6] . The relevant thermodynamic parameters are evaluated via the expressions. C p ( T) R = a − 2 T − 2 + a − 1 T − 1 + a 0 + a 1 T + a 2 T 2 + a 3 T 3 + a 4 T 4.
