Reynolds Number

Reynolds Number

(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

RE: Reynolds Number

You would first need to get the properties of the fluid medium that which you are working with.

I would nto use a flat plate because a wire and a flat plate are going to give you two entirely different numbers, just of the top of my head.
