Hi All!

I have a fundamental question to ask about the Reynolds number. There exits many kinds of Reynolds number like
1. Reynolds number based on momentum thickness
2. Reynolds number based on friction velocity. etc.

I want to know the criteria/situation when to use them. Can you explain some advantages of one kind over the other and its limitations.

Thanking in anticipation.
