Hi,

I know, this question has already been discussed (http://www.cfd-online.com/Forums/ope...roperties.html). But the answer has not been very helpful to me.

I am having exactly the same problem. Im trying to use the hPolynomialThermo for a temperaturedependent Cp.

hPsiMixtureThermo<pureMixture<sutherlandTransport< specieThermo<hPolynomialThermo<perfectGas>>>>
or
hPsiMixtureThermo<pureMixture<constantTransport<sp ecieThermo<hPolynomialThermo<perfectGas>>>>

But OpenFoam gives back

Unknown basicPsiThermo type hPsiMixtureThermo<pureMixture<sutherlandTransport< specieThermo<hPolynomialThermo<perfectGas>>>>>

Valid basicPsiThermo types are:

8
(
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<janafThermo<perfectGas>>>>>
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<eConstThermo<perfectGas>>>>>
hPsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
hPsiThermo<pureMixture<sutherlandTransport<specieT hermo<hConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<constTransport<specieThermo <eConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<hConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
hPsiThermo<pureMixture<sutherlandTransport<specieT hermo<janafThermo<perfectGas>>>>>
)

I can not find anything on the web about that. Which conditions must be met, or which combination must be used, in order to be able to use the hPolynomialThermo?

Another question would be, how to set the polynomial? Something like that:


mixture //keyword
air 1 28.9 //specie
1035.887 -0.255611 0.0006258047 2.627558e-07 //hPolynomialThermo, polynomial for Cp
1.458e-05 110.4; //sutherlandTransport


I woud be very appreciated to get an answer . Thanks!
