I want to do a figure like this one enter image description here

But I can't achieve it. I am a beginners in tikz.

Thanks for your Help. I add the code and the result I get.enter image description here

You can position the node along the path, so you save lines in your code. If you don't want the arrow tip, add - to the path properties, like:

\draw[flow,-] ...

Here's the complete version.
