How to define Fluid properties as a Function of T
 
Hi There Could anyone please tell me that is it possible to make the fluid properties like density as a function of temperature. Is it done by CEL expression?

Dear Md Hamidur,

You got it,

For example,

Dynamic Viscosity = 10 * T [Pa s K^-1]

Density = pabs / R * T

Done..

Hi,

you could do that by changing the material type too, for example by changing constant property gas to Ideal gas equation of state. This could be done by changing material group.
