consentration equation
 

hello
i am simulating a mixer
I have to use Reynolds and peclet namber that peclet namber has
diffusion numbe and couple these together
phases are not important but they similar because of coupling Peclet and Reynolds
and I must active consentration equations
how can active conestration equations?
someone told me if you active consetration equation
Renolds and Peclet will couple together in teory
what are your ideas?
thanks regards

I think you will find the High Resolution scheme does what you are looking for there. That is why it is the recommended advection scheme for most applications.
