Mixing 2 different fluids in T shaped micro-channel
 

I want to know the procedure to solve, mixing 2 different fluids in T shaped micro-channel using fluent. The case is laminar flow. Do i need to check in SPECIES or MULTIPHASE or something else. and how should we see results showing mixed-fraction, stream-lines.

same problem
 

hi
I have the same problem. :)
I want to define a CO2 source in a room. for example a man in a room.
also want to simulate flow around a hous. sulfur is coming out of the stack. it means I want to simulate air with a sulfur source.
thanks

hello
 

If you want to mix two fluids then you have to create two different body parts and mesh it by parts then use different modals whichever you want.
In fluent after initialization of your case use patch option to differentiate between two fluids.
