I recommend you to check this tutorial in user guide link where there is water stream jet case in this case there is a procedure to set up the water vapour transport . Please change the values with your data and you should be able to perform your simulation. If you need further assitance please reach out .
Chapter 29: Steam Jet (ansys.com)
Refer 29.4.2 importing steam jet (ccl)
I hope this solves your problem.
