Things get a lot more complex in multiphase. For instance you have not specified what form the water is in - large globs, pools, a fine mist, large drops or vapour - you would model each of these with a different method.

I need a fine mist, but I do not know where I can choose the method?
It I set in the Workbench> CFX> setup?

Read the documentation about multiphase modelling and do the tutorials. There are many different approaches to multiphase modelling and you have to choose the correct one for your application - and unless you understand what you are modelling and the various options available you will not do a successful model.
