Fluid mixing in micro mixer

I am working on a project and in one part I have use Comsol. This is the first time I am using Comsol and badly need some guidance.
I am working with a micro mixer where I have mix two fluids. In brief, first I want to fill all the channels of the mixer with DI water at a rate of 5 µl/min through inlet one and when all the channels are filled the flow is halted. Then I want to flow a higher index liquid (highly concentrated CaCl2 solution) again at a rate of 5µl/min through the second inlet. So water will be replaced by the solution of cacl2 but it will not be replaced abruptly. There will be a period of transition and the mixer will maintain a homogeneous mix of the two liquids during this period. As a result with time, change of concentration will occur. I want to monitor this change of concentration on a period of 50 second.
Being a new user I am a bit confused which physics should I use and how to couple them in time dependent condition. Any suggestion or advice in order to express my logic properly in Comsol will be great.
Thanks in advance
