Entropy Field Function in CCM?
I want to setup a field function which calculates me the entropy...
I know the basic equation is this:
s21 = cp*ln(T2/T1) - R*ln(p2/p1)
There is a more fundamental equation for calculation the Entropy in a "numerical" way, it is the sum of contributions due to viscous effects and thermal effects. sges = sviscous + sthermal
The equation is in the attachement
How can i implement this function as field function in CCM? I am new to this software, so i need a bit help...
greets and thanks
P.S.: Using a model with constant density...not ideal gas...
Nobody has got an idea?
Generally, i just want to visualize the losses over a blade or some planes.....thougth the entropy is the right way to do this. Is this also with the Rothalpy possible?
Under the node of Tools>Field Functions, you can creating your own field function by right-clicking this node and selecting to create a new one. But note that, STAR CCM has its regulation to write a field function, so please consult the User's guide to resolve your problem. Hope that help.
thanks for your reply, but my question was not how to setup a field function in general. I was looking for a "numerical" formulation of the entropy which is calculated in every point. I want to see the Entropy for example over the pressure side of a airfoil,...
