Currently, I am trying to find the optimal O/F ratio for H2 and O2 in terms of maximal gas escape velocities. I have researched Cp, and Cv values for H2O and H2 extensively, yet I can not find a function of their values depending on temperature. Does anyone know where I could find functions of Cp/Cv values for Hydrogen and water accurate to at least 3000 K? Also, in order to find the overall Cp/Cv value, should I just multiply the mole fraction of each product by it's Cp/Cv value and add all of them up? ((Mol frac. H2)*Cp/Cv(t)(H2)+(Mol frac. H2O)*Cp/Cv(t)(H2O))=Cp/Cv? Finally, I am interested in finding the combustion chamber tempreature. In order to do that, should I equate the enthalpy of a unit mass of reactants with the integral of the combined Cp function (per mass unit) of the products? Tfinal (Delta H)=Integral( Cp(T)(H2O+H2))dT Tinitial I would greatly appreciate any answers to these questions. thank you for taking your time to read this.
