I am trying to simulate a T-mixer, where two streams come in from the opposite ends of a T-joint and are mixed at the junction and leave from the third joint. My reynolds number tells me the flow is always laminar, except for mixing at the junction where it must be turbulent. For simulating such a system, I have defined two zones in the outlet tube based on the development length for laminar flow, one turbulent with k-epsilon solver for viscosity and another laminar. Is this correct?
Also I have not defined a boundary layer in my tubes because I read that boundary layers are just for providing higher mesh densities in some parts of the same volume as compared to the others. Is this correct??
Any help is appreciated, thanks!!!
