How to get the bulk temperature to calculate de heat transfer coefficient
 

I reached with this post https://www.cfd-online.com/Wiki/Ansy..._inaccurate.3F , and I need to change the bulk temperature to reach a correct HTC, but I don't know how to calculate it. I'm new in CFX so if you explain in detail how to calculate it will be helpful. I am working in a blade of a compressor. I suppose that I would need to use Post with some expression, but I'm not sure.
