At least, thats what the standard theory says. It's usually safe to bet that CFD theories don't fit ALL the experimental facts, though.

I still don't know if it is possible to have a “fully developed turbulent flow” over plate?

Hello there, I would like to ask you a question.
I have two pipes which are parallely connected. I have a constant TOTAL FLOW which is divided into two. Diameter1 > Diameter2 and now, when I increase Diameter1 (in order to decrease PRESSURE LOSS), my velocity is decreasing such that it will decrease (Velocity * Diameter) the Re in the first pipe. My question is: I have steady state flow, fully developed, and laminar. Pipe lengths are equal and temperature is constant. Can I say that (given that Qtotal is constant and I am only changing D1) when I decrease pressure loss by increasing diameter, Re number is decreasing. So, shear stress distribution is decreasing as well! or, when I increase reynolds number by decreasing Diameter 1, Pressure loss is increasing, and shear stress distribution is increasing? I have a final presentation tomorrow morning. I am really confused about this result actually. Hope somebody will answer. berkan

how is fully developed flow related to the stream function of the flow?

Ψ=4y((1/3) y^3)
This is the stream function i'm referring to here.
