Hi all,
Please tell me how to define two fluids(air and diesel) in CFX?
I tried the beta feature option, it is working but the temperature rise getting is not correct. It gives same temperature rise for different heat dissipation.

first tab under domain settings, fluid and particle definition, you can add meny fluids to the domain gas or liquid.
There is also a posibility of multispicies simulation in cfx let say if you would like to have multiple gasses and see them mixing.
no beta is needed for this

There are many ways to model multiphase simulations in CFX. You need to choose the correct multiphase model if your simulation is going to be useful. Make sure you do the CFX tutorials and read the CFX documentation so you understand the available models.
