I am wondering how you calculate the Reynolds Number, Re, for wire mov

(OP)
I am wondering how you calculate the Reynolds Number, Re, for wire moving in a fluid. What characteristic dimension do you use; and what criteria do you use to determine a turbulent state?

      My approach would be to use

 Re = vD/viscosity(k)
 v = velocity of wire D = diameter of wire
 viscosity(k) = kinematic viscosity
And to use the criteria for flow over a flat plate. Does this make any sense?

Thank You

You might check Naval Architecture/Marine Engineering resources.  There are many cases of ships towing cables.  I'm sure that the US or British Navy have this information for towed sonar cables but it's probably classified.  There are many commercial examples also.

Good Luck,

Thanks Mark!

I will check into these as resources. I'm sure there are some references in my own field (Wire & Cable Manufacture) but I'm not near sources of literature right now..
