Temperature depence of viscosity of a polymer
Temperature depence of viscosity of a polymer
(OP)
Hi,
I am working on the temperature dependence of viscosity of a polymer.
I would like to model it on ANSY FLUENT et plot a curve on excel.
My problem is within the Arrhenius law:
nu = K*gamma^(n-1)*exp[alpha(1/(T-To) - 1/(T-Talpha)]
I don't get the difference between temperatures To and Talpha.
It says that the both are reference temperature, but i would to know the difference.
Thanks in advance fro your help.

So, I would think that there are two reference viscosities (two values) which are each given at their respective reference temperature, To and Ta.

Some quick research found the above link and it offers one interpretation for To and Talpha.

Hopefully, the OP learned what they were looking for too!
