For the viscosity, you can type in a mathematical expression that depends on the species' concentrations, temperature, etc.

I already have my mathematical function for the viscosity however I want to link it with the CFD results. For example I have the "T" variable in my equation for temperature but I want Comsol to put temperature value as it calculates it along the pipe wall. Which expression do I have to put instead of T.

I guess you can use non local coupling 'Average'. It calculates the average temperature over the domain and you can use this as a varaible.
