I have a problem with the choice of the parameters of the ideal-gas for the study of supersonic-hypersonic external a comprimibile flow 3D.

My choices have been:

Density --> ideal-gas

Cp --> constant

Thermal conducivity --> constant

Viscosity --> sutherland (three coefficent method)

Molecular wheight -- >constant

I would want hopes if the choices for the Cp and the Thermal Conducivity are adapted to my case

thanks in advance payment

Why can't you try kinetic theory for Cp and K. Don't forget to specify Degree of freedom if you are using kinetic theory for Cp. Rahul
