Hello all,

I have a pair of questions about a simulation. I will be grateful if you could suggest me something.

My case is a tube of 8 mm of diameter of 4 m long. I introduce water at 0.5 m/s and I want to simulate the flow through the tube. But the fluid contains a component that is reacting (micelles) and then I have 2 effects:

- Enthalpy of reaction
- Viscosity increasement

These 2 variables depend on conversion and conversion depends on time. Then I must simulate heat of reaction and viscosity depending on time. Where can I introduce these formulas?

Thanks in advance!
Miquel
